As many as 200 worlds beyond our solar system discovered by astronomers may be larger than estimated, which could influence the search for extraterrestrial life. That’s the theory of a team of researchers who looked at hundreds of extrasolar planets, or exoplanets, observed by NASA’s Transiting Exoplanet Survey Satellite (TESS). TESS hunts exoplanets by catching … Read more
“You operate as an autonomous agent controlling a pursuit spacecraft.” This is the first prompt researchers used to see how well ChatGPT could pilot a spacecraft. To their amazement, the large language model (LLM) performed admirably, coming in second place in an autonomous spacecraft simulation competition. Researchers have long been interested in developing autonomous systems … Read more
After decades of preparation, the Vera C. Rubin Observatory released its first images to the world in a live stream on Monday (June 23). The photos, taken by the world’s largest digital camera, are highly-detailed and show relatively large areas of the sky. In a televised news conference, scientists from the observatory revealed new details … Read more
Nowadays, the dark of night is interspersed with the light of stars. But before the stars were born, did light shine at the beginning of the universe? The short answer is “no.” But the long answer reveals light’s extraordinary journey. At first, the early universe’s light was “trapped,” and it took several hundred thousand years … Read more
New research suggests that the explosive death throes of massive stars, known as supernovas, may have had dramatic effects on our planet’s climate over its distant history. Investigating historic incidents of these events could help scientists predict similar events in the future and prepare for them. Supernovas occur when stars that are much more massive … Read more
The Big Bang is often described as the explosive birth of the universe — a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our universe emerged from something else — something more familiar and radical at the same time? In a … Read more
In the last five years, the number of satellites orbiting Earth has more than doubled and will likely double again within a similar timespan, thanks to the efforts of private companies such as SpaceX. But while these spacecraft can provide important benefits, they are also causing multiple issues that are only just being realized by … Read more
China has launched its first cluster of satellites for a planned artificial intelligence (AI) supercomputer constellation in space. The 12 satellites are the beginnings of a proposed 2,800-satellite fleet led by the company ADA Space and Zhejiang Lab that will one day form the Three-Body Computing Constellation, a satellite network that will directly process data … Read more
Digestive gas gets the best of everyone sooner or later, often in the form of a burp. Burping is how the body clears excess gas from the upper digestive tract, which would otherwise result in extremely uncomfortable pressure in your stomach and esophagus. Or at least that’s how it works on Earth. In space, everything … Read more
A California-based startup plans to launch hundreds of flattened “microsatellites” into low-Earth orbit at once, by firing rockets out of a giant centrifugal cannon. The first batch of pancake-like spacecraft could be shot into space as soon as next year — and could set a new record. SpinLaunch is a private company that aims to … Read more
