Feeling sluggish and crabby? Got cloudy skies? You might be suffering from SDS.

The Milky Way's Galactic Center and Bulge are shrouded in thick dust and tightly-packed with stars. It's a tough region to observe, but the Nancy Gracy Roman Space Telescope is built for the task. Its Galactic Bulge Time-Domain Survey will find more than 100,000 exoplanets, along with stars, black holes, neutron stars, and even rogue planets.

These polar bears appear to be maintaining their physical health despite the loss of sea ice—their preferred hunting grounds

Shrinking sea ice has made life harder for polar bears in many parts of the Arctic, but the population in Svalbard seems to be thriving

A new image from NASA’s James Webb Space Telescope of a portion of the Helix Nebula highlights comet-like knots, fierce stellar winds, and layers of gas shed off by a dying star interacting with its surrounding environment. Webb’s image also shows the stark transition between the hottest gas to the coolest gas as the shell expands out from the central white dwarf.

New CT scanners can build a 3D model of your carry-on, helping airport staff spot risks without making you unpack or decant liquids into tiny bottles

The crew of four will launch no earlier than Wednesday 11 February at 11:00 GMT/12:00 CET (06:00 EST) from Space Launch Complex 40 at Cape Canaveral Space Force Station, Florida, USA. The next available opportunities are Thursday 12 February at 10:38 GMT/11:38 CET (05:38 EST) and Friday 13 February at 10:15 GMT/11:15 CET (05:15 EST).  

Jupiter’s atmosphere and clouds have mesmerized stargazers for centuries, as their multi-colored, swirling layers can easily be viewed from powerful telescopes on Earth. However, NASA’s Juno spacecraft has upped the ante regarding our understanding of Jupiter’s atmospheric features, having revealed them in breathtaking detail. This includes images of massive lightning storms, clouds swallowing clouds, polar vortices, and powerful jet streams. Yet, despite its beauty and wonder, scientists are still puzzled about the processes occurring deep inside Jupiter’s atmosphere that result in these incredible features.

The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the Universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at CTIO, a Program of NSF NOIRLab. Their completed analysis combines all six years of data for the first time and yields constraints on the Universe's expansion history that are twice as tight as past analyses.

After months of protests led by Nobel laureate Reinhard Genzel, the American energy company AES Andes has abandoned plans to build a massive solar and wind facility just kilometres from one of the world's premier telescope sites. The decision preserves the pristine night skies above Chile's Paranal Observatory, where the European Southern Observatory operates some of humanity's most powerful eyes on the universe.

Nearly a century after Edwin Hubble discovered the universe's expansion, astronomers have finally explained the nagging mystery of why most nearby galaxies rush away from us as if the Milky Way's gravity doesn't exist? The answer lies in a vast, flat sheet of dark matter stretching tens of millions of light years around us, with empty voids above and below that make the expansion appear smoother than it should.

Researchers using machine learning have discovered hundreds of mysterious bright streaks on Mercury's surface that appear to be caused by gases escaping from the planet's interior. The finding suggests the Solar System's smallest planet isn't the static, geologically dead world we thought it was, Mercury might still be active today, continuously releasing material into space even billions of years after its formation.
