Elon Musk Slammed Online by Chinese – Latest news headlines

Chinese citizens lashed out online against billionaire Tesla founder Elon Musk’s space ambitions on Monday after China complained that its space station was forced to take evasive action to avoid collision with satellites launched by Musk’s Starlink programme.

The satellites from Starlink Internet Services, a division of Musk’s SpaceX aerospace company, had two “close encounters” with the Chinese space station on July 1 and October 21, according to a document submitted by China earlier this month to the UN’s space agency.

“For safety reasons, the China Space Station implemented preventive collision avoidance control,” China said in a document published on the website of the United Nations Office for Outer Space Affairs.

The complaints have not been independently verified. SpaceX did not immediately respond to a request for comment.

In a post on China’s Twitter-like Weibo microblogging platform on Monday, one user said Starlink’s satellites were “just a pile of space junk”, while another described them as “American space warfare weapons”.

With nearly 30,000 satellites and other debris believed to be orbiting the planet, scientists have urged governments to share data to reduce the risk of catastrophic space collisions.

SpaceX alone has deployed nearly 1,900 satellites to serve its Starlink broadband network, and is planning more.

“The risks of Starlink are being gradually exposed, the whole human race will pay for their business activities,” a user posting under the name Chen Haiying said on Weibo.

US space agency NASA was forced to abruptly call off a spacewalk at the end of November, citing risks posed by space debris. Musk tweeted in response that some Starlink satellite orbits had been adjusted to reduce the possibility of collisions.

China began constructing the space station in April with the launch of Tianhe, the largest of its three modules. The station is expected to be completed by the end of 2022 after four crewed missions.

Musk has become a well-known figure in China, though Tesla’s electric-vehicle business has come under growing scrutiny from regulators, especially after a customer climbed on top of a Tesla car at the Shanghai auto show in April to protest against poor customer service.

Latest News Today – Hubble Telescope Finds First Evidence of Water Vapour on

Astronomers have found the first evidence of water vapour in the atmosphere of Jupiter’s moon Ganymede, the largest moon in the Solar System. They believe Ganymede may hold more water than all of Earth’s oceans. But finding water in liquid form there is difficult. The temperatures are so cold that all the water on the surface is frozen solid and the ocean lies roughly 100 miles (160km) below the crust, said the European Space Agency. Still, scientists believe finding water is a crucial first step in knowing whether life could exist on a celestial body or not. The astronomers analysed archival datasets of the Hubble Telescope over the past two decades to come to this conclusion.

The ESA said identifying liquid water on other planets is crucial to understand whether they are habitable.

The research is based on datasets going back to 1998, when Hubble took the first ultraviolet (UV) pictures of Ganymede. These images revealed a particular pattern in the observed emissions from the moon’s atmosphere which was somewhat similar to those observed on Earth and other planets with magnetic fields.

Scientists later found that Ganymede’s surface temperature varies extremely throughout the day. Around noon, it may become warm enough that the icy surface releases some small amounts of water molecules. Since the oceans lay miles below the crust, it is unlikely that the water vapour could be from them.

“Initially only the O2 (molecular oxygen) had been observed,” said lead researcher Lorenz Roth, adding that this is produced when charged particles erode the ice surface.

He said the water vapour his team has found originates from ice sublimation.

NASA, too, has released a video that describes the new finding. Watch it here:

This development has led to curiosity ahead of ESA’s planned Jupiter Icy Moons Explorer (JUICE) mission in 2022. The mission is expected to reach Jupiter in 2029 and will spend the next three years studying Jupiter and three of its largest moons, including Ganymede.

Latest News Today – NASA Mars Helicopter Inegnuity Gears Up for 10th Flight,

NASA’s Ingenuity helicopter is all set to make its tenth flight on Mars and officials said that it could happen on July 24. Ingenuity, which arrived on the Red Planet aboard the Mars Perseverance rover on February 18, is the first to have flown on a terrestrial planet other than Earth. The space agency said that the rotorcraft’s ninth flight was different from the ones it had undertaken before. Not only did it break the records of flight duration and cruise speed but also quadrupled the distance flown between two airfields. 

NASA said in a note published on its website, that one of the defining aspects of Ingenuity’s last flight, that lasted 2 minute and 46 seconds, was that it successfully negotiated a terrain called “Seitah.” The terrain would have been difficult to cover using a ground vehicle like the Perseverance rover. The tenth flight will investigate “Raised Ridges,” a collection of rock features inside Mars’ Jezero Crater, according to a report by Space.com. 

On July 23, NASA also posted a picture of the “Little (Mars) Helicopter” on Instagram. The agency described the ninth flight as a “nail-biter.” It said that the flight was explicitly designed to have science value by providing the first close view of major science targets that the rover will not reach for quite some time.

The post, furthermore, read, “This was made possible by a team of NASA Ames helicopter experts who assisted NASA JPL’s Ingenuity team in making sure the technology demonstrator had the best chance for success in flying in the super-thin atmosphere of the Red Planet.”

The photograph headlining the post was captured on June 15, 2021, by the Mars Perseverance rover using its left Mastcam-Z Camera, composed of a pair of cameras located high on the rover’s mast, the agency said.

Latest News Today – NASA Posts Image of Lagoon Nebula That Shows a

NASA has shared a stunning image of the Lagoon Nebula, a giant blue cloud of gas and dust where stars are currently forming. The image had thousands of stars, or giant flares, twinkling like dots on a massive black canvas. The Lagoon Nebula, also known as NGC 6523 or Messier 8, is located some 4,400 light-years from Earth, within our own Milky Way galaxy. The space agency’s Chandra X-Ray Observatory, a telescope designed to detect X-ray emission from very hot regions of the universe, found it during one of the largest surveys of star formation ever conducted in X-rays.

In an Instagram post, NASA said the survey covered some 24,000 individual stars in 40 different regions. It added that the survey conducted by Chandra X-ray Observatory will help scientists understand the link between the powerful flares or outbursts from young stars and the impact they could have on planets in orbit around them.

Stressing the significance of discoveries like these, NASA said scientists have argued over the past two decades that these giant flares can help the still-forming stars by driving gas away from disks of material surrounding them. “This can trigger the formation of pebbles and other small rocky material that is a crucial step for planets to form,” it said. But these flares can also damage the planets that have already formed by blasting them with powerful radiation.

The discovery has left more than seven lakh Instagram users stunned who have shared their appreciation by liking the image. Several of them also left comments.

“I love you NASA,” said a person with the username “h_.mariwan”.

“It. Almost. Doesn’t. Look. Real,” commented Juny. M.

“I wish there was the speed of light. If the speed of light were found, the new holiday route for humans would probably be different planets. hope we succeed,” Melis Kaya mused.

Latest News Today – Hubble Space Telescope Down for Past Few Days, Says NASA

The Hubble Space Telescope, which has been peering into the universe for more than 30 years, has been down for the past few days, NASA said Friday.

The problem is a payload computer that stopped working last Sunday, the US space agency said.

It insisted the telescope itself and scientific instruments that accompany it are “in good health.”

“The payload computer’s purpose is to control and coordinate the science instruments and monitor them for health and safety purposes,” NASA said.

An attempt to restart it on Monday failed.

NASA said initial evidence pointed to a degrading computer memory module as the source of the computer problem.

An attempt to switch to a back-up memory module also failed.

The technology for the payload computer dates back to the 1980s, and it was replaced during maintenance work in 2009.

Launched in 1990, the Hubble Space Telescope revolutionised the world of astronomy and changed our vision of the universe as it sent back images of the solar system, the Milky Way and distant galaxies.

A new and more powerful one, called the James Webb Space Telescope, is scheduled to be deployed late this year. It is designed to peer deeper into the cosmos than ever before.

Latest News Today – NASA Shares Spectacular Image of Galaxies Merging 140

NASA has released yet another fascinating photograph of two swirling galaxies merging in a galactic system 140 million light-years from the Earth. As these two galaxies become one, shock waves rumble through both of them and trigger waves of new star formation, the American space agency explains. Some of these stars are very large and live brief but violent lives. The image showed two oval-shaped objects in close proximity emitting bundles of blue X-rays that illuminate the surrounding areas. Data from NASA’s Chandra Observatory shows 25 bright X-ray sources sprinkled throughout the galactic system.

NASA launched Chandra X-Ray Observatory in 1999. Since then, it’s been the agency’s flagship mission for X-ray astronomy and takes its place among the fleet of “Great Observatories”.

NASA titled the Instagram post, “Blended, not stirred, please” and said that the galactic system captured by its space-based telescopes is named Arp 299. Out of the 25 X-ray sources in the image, 14 are such strong emitters that astronomers have categorised them as “ultra-luminous X-ray sources,” or ULXs.

“These ULXs are likely binary systems where a black hole or neutron star is pulling material from a companion star,” the space agency said. NASA added that the image contains X-ray data from the Chandra observatory, the Hubble Space Telescope, and the NuSTAR X-ray telescope.

Soon after the image was posted on social media, astronomy enthusiasts flocked there to appreciate the exquisiteness of this celestial process. Most of the Instagram users were wowed by the image and praised its quality. The image had more than 5,46,000 likes within 13 hours.

A person, who goes by the username wizard.b0i, also asked: “Is there a wallpaper of this picture available? PC and mobile?”

Luckily, the Chandra Observatory website says that images can be searched and downloaded to make them wallpapers on phones and tablets by visiting the web page:

Latest News Today – Andromeda Galaxy Zoom-Out Video With Over 100 Million

Andromeda Galaxy’s vastness is captured perfectly in a zoom-out video that was shared by World and Science, a Twitter handle that frequently shares interesting stories from the world of science. The video of Andromeda Galaxy, also known as Messier 31 or M31, has left users on the micro-blogging site awestruck. The sharp zoom0out clip shows over 100 million celestial bodies. The clip begins with the camera moving to the right before it zooms out and reveals what’s undoubtedly a heavenly view of the M31.  

“Mind-blowing! A zoom out of the sharpest view of the Andromeda Galaxy ever, showing more than 100 million stars!” wrote World and Science on June 9 and shared the clip with its 2.1 million followers. Midway through the zoom out video, the camera slows down a bit and reveals the galaxy full of innumerable stars, some easily identifiable due to their size. At the time of writing, the video had already generated quite an excitement, with over 340,000 views, 10,500 likes, and over 3,200 retweets.

Reacting to it, Teen Wolf star Ian Bohen tweeted, “Great perspective for all those who think we’re alone out here,” he wrote.

Another user (@idealust) wondered how there could be no life out there. “Staggeringly huge amount of planets around those stars. The trick is, is it alive during our ability to find it? Too much to search. Not enough time. Such a paradox,” the tweet read.

“It’s also incredible to think how far apart these stars really are when they all look so close together in the photo,” user Chilly MIV commented

Here are some more reactions to the fascinating view of the Andromeda Galaxy.

According to NASA, the Andromeda galaxy is a majestic spiral of perhaps as many as 1 trillion stars, twice the number in our Milky Way. It’s so close to us that the galaxy appears as “a cigar-shaped smudge of light high in the autumn sky,” said the space agency. It added that the M31 is at a distance of 2.5 million light-years from us. 

In another post last month, NASA recalled that less than 100 years ago, many astronomers thought the Milky Way was the only galaxy in the universe. It said that even though astronomers debated the existence of other galaxies, it took Edwin Hubble’s observations of the Great Andromeda Nebula to confirm that it was far too distant to be part of the Milky Way. The Great Andromeda Nebula then became the Andromeda Galaxy, and astronomers recognised that our universe was much bigger than humanity could envision.

Latest News Today – Asteroid 2021 KT1 Considered ‘Potentially Hazardous’ by

2021 KT1, a “potentially hazardous” asteroid is passing near the Earth on Tuesday (June 1), NASA has warned. The asteroid will make a close approach to the Earth at around 10:24am EDT (7:54pm IST). The gigantic rock would fly past our planet with a distance of around 4.5 million miles. Some other asteroids are also expected to zip past the Earth later this week. However, those would be significantly smaller than the 2021 KT1.

NASA has said on its Jet Propulsion Laboratory (JPL) website that the 2021 KT1 asteroid could be around 186 metres in size. This is twice as big as the Statue of Liberty, which is 93 metres in height.

The asteroid is not likely to hit the Earth as it would be 4.5 million miles away at the closest point. However, NASA considers any asteroid potentially hazardous when it comes within 4.6 million miles of the Earth and is larger than 150 metres.

There aren’t any references to confirm whether or not the asteroid would affect the Earth. Nonetheless, NASA says that people should not be overly concerned about a Near-Earth Object (NEO) such as an asteroid impacting the Earth. “The threat to any one person from auto accidents, disease, other natural disasters and a variety of other problems is much higher than the threat from NEOs,” the space agency noted on its Center for Near Earth Object Studies (CNEOS) website.

Scientists, however, believe that chances of the Earth being impacted by NEOs over long periods of time are “not negligible” and thus NASA and other space agencies around the world actively monitor asteroid and comet moments.

In addition to the 2021 KT1, some smaller asteroids are passing near the Earth in the coming days. Those asteroids are expected to be of up to 21 metres in size.

Latest News Today – International Space Station Shares Spectacular

International Space Station (ISS) has shared some spectacular photos of the Earth, captured by the astronauts stationed on it. In a new Instagram post, the ISS shared four different photos of “the Earth’s colours” — capturing our home planet “from the city lights to the hues of an orbital sunrise.” It also added “how vivid our planet is when pictured from the space station.”

So, what are the amazing sights in the newest set of photos from the space station? The first image is of Mauritius and Réunion Island on the Indian Ocean at night, with the glittering lights marking their boundaries in the dark sea.

In the second photo, we can see the Sun’s glint beaming off the Tasman Sea on the south-eastern coast of New South Wales, Australia.

The third is a breathtaking photograph of night lights of Italy during and orbital twilight, while the fourth shows captivating hues of an orbital sunrise in far easter Asia.

The ISS shared these pictures with 7.6 million of their Instagram followers. So far, over 257,000 people have liked the post.

While one user who goes by username im_not_jeremyshaffer requested ISS to never “stop sharing these photos because they are always fascinating, and give a few moments relief from everyday life,” another, who goes by the name jobbepilgaard felt it must be “surreal looking down on entire countries like that.”

A third user, jrenato, also wanted to know if the ISS had “any picture of the last lunar eclipse.”

In another post, the space station shared four photos of the lunar eclipse that had occurred on Wednesday. The ISS captioned the photo, “The Moon pictured during a lunar eclipse on Wednesday is seen from the space station as it orbited over 260 miles above the Earth.”

Not only does the ISS serve as a home to astronauts but is also a science laboratory. Several countries have worked together to build and use the space station. It is made of parts that were assembled in space by astronauts. The space station orbits the Earth at an average altitude of approximately 250 miles (402 kiometres), NASA says.

The US space agency is using the ISS to learn more about living and working in space and believes the lessons will make it possible to send humans farther into space than ever before.

Latest News Today – Fabric of Our Galaxy: NASA Releases Stunning Image of

NASA shared a stunning panoramic view of the Milky Way’s galactic centre on Instagram. Explaining the photo, the space agency said threads of superheated gas and magnetic fields weave a tapestry of energy at the centre of the Milky Way galaxy. NASA captioned the post, “The fabric of our galaxy.” This image of the cosmic masterpiece was created after using data received from NASA’s Chandra X-Ray Observatory and the MeerKAT radio telescope in South Africa. In the post, the agency said that X-rays from Chandra are orange, green, blue, and purple, showing different energies, and the radio data from MeerKAT are shown in lilac and grey.

It further wrote that “unravelling these threads taught us what the weather was like in that region of space.” The weather, according to NASA, is determined by “volatile phenomena such as supernova explosions and outbursts of matter near the bright centre of the cluster,” where Sagittarius A — a supermassive black hole — is located. It said the combination of X-ray and radio views allowed us to “see magnetic fields that have aligned in different directions, collided, and became twisted around each other in a process called magnetic reconnection.”

On its website, NASA said that the new panorama of the galactic centre builds on previous surveys from Chandra and other telescopes. It adds that the latest version expands Chandra’s high-energy view farther above and below the plane of the Galaxy — that is, the disk where most of the Galaxy’s stars reside — than previous imaging campaigns.

NASA said one thread, in particular, was intriguing, for it had X-ray and radio emission intertwined. “It points perpendicular to the plane of the galaxy and is about 20 light-years long but only one-hundredth that size in width,” the space agency said.

On Instagram, users reacted to the panoramic view of the galaxy, calling it “unreal” and “breathtaking” among other things. The post has been liked by over 918,110 users.
