Shimmering ejections emitted by two actively forming stars make up Lynds 483 (L483). High-resolution near-infrared light captured by NASA’s James Webb Space Telescope shows incredible new detail and structure within these lobes, including asymmetrical lines that appear to run into one another. L483 is 650 light-years away in the constellation Serpens.

SpaceX launched its third mission of the year for the United States' spy satellite agency today (March 24), the 19th anniversary of the company's first-ever liftoff.

Telescope optics can be made of mirrors or lenses, but in both cases, they're bulky and need to follow a strict mathematical curve to focus light. Researchers have shown that it's possible to make a completely flat lens that focuses light. Traditionally, this has been done with Fresnel lenses, but they distort colors. Their new technique carves tiny concentric rings into a substrate that matches the wavelengths of different colors, allowing a full-color, in-focus image.

With season two of Star Wars: Andor hitting the small screen on April 22, now is the time to get a Disney Plus subscription bundle and it's 72% off.

A previously undisclosed FEMA review could block disaster assistance to millions of undocumented people and deter legal immigrants from seeking help in extreme weather

The observation of titanic jets emerging from the supermassive black hole at the heart of a distant galaxy could be a grim prediction of the Milky Way's future.

We’ve pumped huge amounts of carbon dioxide into the atmosphere that needs to be paid back. Large animals like wolves, bison and whales may already be tackling the problem

The upcoming partial solar eclipse on March 29 is the perfect time to watch the moon hide and then reveal dark patches on the surface of the sun.

One of the surprising discoveries of the James Webb Space Telescope (JWST) is that galaxies formed very early in the Universe. JWST has discovered about two dozen galaxies at a redshift of around z = 14, meaning that we see them at a time when the cosmos was just 300-500 million years old. The most distant galaxy, JADES-GS-z14-0, is seen at an age of less than 300 million years. All of these galaxies are rich with stars and have a basic structure similar to what we see in more modern galaxies. This discovery challenged our understanding of galactic evolution. Now a new discovery challenges it even further.

SpaceX plans to make spaceflight history this month, by launching the first crewed mission to explore Earth's polar regions.

The Hubble Space Telescope captured an image of a star and a spiral galaxy, both in the constellation Virgo. But the photo is an optical illusion.

The NASA/ESA/CSA James Webb Space Telescope has captured a beautiful juxtaposition of the nearby protostellar outflow known as Herbig-Haro 49/50 with a perfectly positioned, more distant spiral galaxy. Due to the close proximity of this Herbig-Haro object to Earth, this new composite infrared image of the outflow from a young star allows researchers to examine details on small spatial scales like never before. With Webb, we can better understand how the jet activity associated with the formation of young stars can affect the environment surrounding them.

Astronomers have tracked several meteorites that dropped in on Earth back to their origin, space rocks in the main asteroid belt between Mars and Jupiter.

Space-based solar power is one step closer to reality, now that Florida startup Star Catcher has successfully beamed energy across the Jacksonville Jaguars' stadium.
