Massive stars about eight times more massive than the Sun explode as supernovae at the end of their lives. The explosions, which leave behind a black hole or a neutron star, are so energetic they can outshine their host galaxies for months. However, astronomers appear to have spotted a massive star that skipped the explosion and turned directly into a black hole.

New 'Star Wars' trilogy set at Lucasfilm with 'Rebels' writer and producer Simon Kinberg
On top of the previously announced standalone big-screen projects, a new trilogy of Star Wars movies is now in active development at Lucasfilm.
eROSITA All-Sky Survey Takes the Local Hot Bubble’s Temperature
About half a century ago, astronomers theorized that the Solar System is situated in a low-density hot gas environment. This hot gas emits soft X-rays that displace the dust in the local interstellar medium (ISM), creating what is known as the Local Hot Bubble (LHB). This theory arose to explain the ubiquitous soft X-ray background (below 0.2 keV) and the lack of dust in our cosmic neighborhood. This theory has faced some challenges over the years, including the discovery that solar wind and neutral atoms interact with the heliosphere, leading to similar emissions of soft X-rays.
An asteroid hit Earth just hours after being detected. It was the 3rd 'imminent impactor' of 2024
A small asteroid burned up in Earth's atmosphere off the coast of California just hours after being discovered and before impact monitoring systems had registered its trajectory.
China planning to build its own version of SpaceX's Starship

Save $300 on the best-motorized telescope before Black Friday
The Celestron NexStar 8SE is on offer for $300 off ahead of Black Friday, which is cheaper than when it was on offer over Prime Day.
An Explanation for Rogue Planets. They Were Eroded Down by Hot Stars
The dividing line between stars and planets is that stars have enough mass to fuse hydrogen into helium to produce their own light, while planets aren’t massive enough to produce core fusion. It’s generally a good way to divide them, except for brown dwarfs. These are bodies with a mass of about 15–80 Jupiters, so they are large enough to fuse deuterium but can’t generate helium. Another way to distinguish planets and stars is how they form. Stars form by the gravitational collapse of gas and dust within a molecular cloud, which allows them to gather mass on a short cosmic timescale. Planets, on the other hand, form by the gradual accumulation of gas and dust within the accretion disk of a young star. But again, that line becomes fuzzy for brown dwarfs.
On ancient Mars, carbon dioxide ice kept the water running. Here's how
Huge shells of frozen carbon dioxide at Mars' south polar cap resulted in subsurface meltwater, which fed a huge system of rivers, lakes and even a sea, a new study suggests.
