Astronomers worldwide are tracking a massive space rock hurtling through our solar system. The odds of Earth being hit by the asteroid, called YR4, have increased. While still far from certain, scientists are paying very close attention to the possibility of this city-killer asteroid making contact with Earth in 2032. Watch in for more details!

The increasing presence of space junk in Earth’s orbit is posing an escalating threat to air travel, with new research highlighting the risks associated with uncontrolled rocket debris re-entering the atmosphere. Watch this report for more details!

Astronomers have identified "Quipu," the largest known structure in the universe, stretching billions of light-years across. This cosmic giant challenges our understanding of the universe's formation and scale. Scientists are now studying its origins and significance.

Falling Space Junk: A disaster waiting to happen?

According to a new study, the chances of a falling piece of space debris striking an airplane are growing. While it has not happened yet, it may prove catastrophic in case it happens.
Researchers from the University of British Columbia in Canada modelled the distribution of planes in the sky and compared them to records of uncontrolled rocket body reentries.
With the increase in deployment of satellites, like SpaceX's Starlink, and more planes flying in the sky, the risk of such a collision is increasing rapidly. Despite the existence of technology that can track falling space debris, it still remains a major concern.
&ldquo;The highest-density regions, around major airports, have a 0.8 per cent chance per year of being affected by an uncontrolled reentry,&rdquo; the researchers wrote in the paper that was published in Scientific Reports.

&ldquo;This rate rises to 26 per cent for larger but still busy areas of airspace, such as that found in the northeastern United States, northern Europe, or around major cities in the Asia-Pacific region.&rdquo;
According to The Aerospace Corporation, the chances of a fatal plane collision with an object falling from space was near 1 in 100,000 in 2021.
Even the smallest piece of a rocket or satellite falling may be enough to bring a plane down, risking passenger safety. As per the estimates, something as small as one gram may cause damage if it hits an aircraft&rsquo;s windshield or engine.

As the chances of such events grow, the probability that parts of airspace will remain closed may also increase. This will make the skies congested and lead to delay and cancellation of flights.
&ldquo;This situation puts national authorities in a dilemma &ndash; to close airspace or not &ndash; with safety and economic implications either way,&rdquo; write the researchers.
Identifying reentry paths of space debris is often challenging, implying that larger areas of airspace would require being shut down as a precaution. A similar thing happened with the Long March 5B rocket body in 2022.

According to the researchers, the solution to this is more investment in controlled rocket reentry. While the technology allows it, less than 35 per cent of launches use it, leaving a burden of safety for the aviation industry.
Although efforts continue to improve safety inside and outside the Earth&rsquo;s atmosphere, it requires buy-in from government agencies and private companies.&nbsp;
&ldquo;Over 2,300 rocket bodies are already in orbit and will eventually reenter in an uncontrolled manner,&rdquo; wrote the researchers. &ldquo;Airspace authorities will face the challenge of uncontrolled reentries for decades to come.&rdquo;

Astronaut Sunita Williams, who has been stranded in space for the past eight months, said that she has lost the capacity to do a lot of fundamental tasks, stressing that she does not even know what it's like to walk.&nbsp;
Williams, in a video conference with classmates at Needham High School in Massachusetts on Monday, said that she has been trying to remember what it's like to walk.&nbsp;
Saying, "I haven't laid down", Williams said, "I've been up here long enough, right now I've been trying to remember what it's like to walk. I haven't walked. I haven't sat down.&rdquo;

Due to delays, their mission has now been extended to 10 months, with their return planned for late March or early April.
NASA had earlier determined that the duo would come home on Dragon because of lingering uncertainties surrounding Starliner.

NASA leadership repeatedly stressed on multiple forums that Wilmore and Williams were not &ldquo;stranded,&rdquo; but that the Starliner didn&rsquo;t have enough assurances around it to support a crewed trip back to Earth.

Science & technology Trending: Williams, in a video conference with classmates at Needham High School, said that she has been trying to remember what it's like to walk. 

Astronaut Sunita Williams, who has been stranded in space for the past eight months, said that she has lost the capacity to do a lot of fundamental tasks, stressing that she does not even know what it's like to walk. Williams, in a video conference with classmates at Needham High School in Massachusetts on Monday, said that she has been trying to remember what it's like to walk. Saying, "I haven't laid down", Williams said, "I've been up here long enough, right now I've been trying to remember what it's like to walk. I haven't walked. I haven't sat down.” Also read: Trump orders Musk to bring astronauts Sunita Williams, Butch Wilmore home She has spent around 234 days in microgravity. “You can just close your eyes and float where you are right here. We initially thought it might be around a month, but the extension turned out to be quite different,” she said.

Comet visits to the inner solar system continue in 2025. An icy space rock from the Oort cloud will come extremely close to the Sun in the second week of January, and if it manages to survive the trip, it would make for a wonderful spectacle from Earth as well.
Comet ATLAS (C/2024) G3 will reach its closest point to the sun on Jan 13, 2025. At perihelion, the comet will be just 8.3 million miles (13.5 million kilometres) from the sun. On the same day, Comet G3 will also appear at its brightest from Earth. Notably, Mercury is nearly 29 million miles (47 million kilometres) from the sun.
It was discovered on April 5, 2024, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) system of telescopes.
However, whether or not it will survive the heat of the sun is still not clear. If it does, it would be the brightest comet of 2025.

But it would be visible to the naked eye only in the Southern Hemisphere. In 2024, when Comet A3 travelled to the inside of the solar system, it was spotted by several stargazers in both the Southern and Northern Hemispheres.
Comet G3 is expected to become as bright as Venus. According to The Planetary Society, the comet's brightness would be at a magnitude of -4.5 during January 2025 and it will travel in the constellation Sagittarius.

<h2>Will Comet G3 survive the Sun?</h2>
The comet will get too close to the sun, making experts wonder whether it will survive the trip. Experts are hopeful since its orbital path suggests that the last time it visited the inner solar system was about 160,000 years ago. This means that it likely escaped unscathed at the time.&nbsp;
"It will be strongly heated and may not survive," said Nick James, director of the British Astronomical Association's comet section, as per Space.com.
"But if it does, it may be an impressive object in the evening sky from the southern hemisphere after perihelion."
James also cautioned that since the comet will be extremely close to the sun, only "experienced observers" should attempt to view it as otherwise it might prove dangerous.
The bright moon around the time of comet G3's perihelion will also make viewing it tough. January's full "Cold Moon" will rise opposite the comet on the eastern horizon on Jan 13.

Comet ATLAS (C/2024) G3 is the latest visitor to the solar system and might become visible on January 13. But experts are worried that the sun might kill it.
