This Photonic Crystal Bends Light Like a Black Hole
One of the first observational tests of general relativity was that the path of light bends in the presence of mass. Not only refracts the way light changes direction as it enters glass or other transparent materials, but bends along a curved bath. This effect is central to a range of physical phenomena, from black holes to gravitational lensing to observations of dark matter. But because the effect is so tiny on human scales, we can’t study it easily in the lab. That could change in the future thanks to a new discovery using distorted photonic crystals.
The West Antarctic Ice Sheet is melting, and it's too late to stop it
A best-case projection that meets ambitious Paris Accord targets suggests the West Antarctic Ice Sheet will melt three times faster in the 21st century than it did in the 20th.
The mysterious dimming of supergiant star Betelgeuse may finally be explained (photo)
Images released by the European Southern Observatory may reveal why Betelgeuse dimmed in 2019.
Civilizations are Probably Spreading Quickly Through the Universe
The Search for Extraterrestrial Intelligence (SETI) has always been plagued by uncertainty. With only one habitable planet (Earth) and one technologically advanced civilization (humanity) as examples, scientists are still confined to theorizing where other intelligent life forms could be (and what they might be up to). Sixty years later, the answer to Fermi’s famous question (“Where is Everybody?”) remains unanswered. On the plus side, this presents us with many opportunities to hypothesize possible locations, activities, and technosignatures that future observations can test.
Astronomers Want JWST to Study the Milky Way Core for Hundreds of Hours
To understand the Universe, we need to understand the extreme processes that shape it and drive its evolution. Things like supermassive black holes (SMBHs,) supernovae, massive reservoirs of dense gas, and crowds of stars both on and off the main sequence. Fortunately there’s a place where these objects dwell in close proximity to one another: the Milky Way’s Galactic Center (GC.)
1st-ever radio images of an annular solar eclipse showcase the sun's extended corona
Scientists used the new Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA) in California to capture radio images of October's annular eclipse.
China continues remote-sensing buildup with new launch of Yaogan satellites (video)
A Long March 2D rocket launched into the night sky above the Xichang Satellite Launch Center in southwest China on Oct. 23, carrying three more Yaogan 39 satellites to orbit.
China unveils Shenzhou 17 astronauts launching to Tiangong space station tonight (video)
China has revealed its latest crew of astronauts set for a six-month-long mission to the Tiangong space station today.
SpaceX to launch final piece of NASA's 1st two-way laser communications relay
NASA's ILLUMA-T demonstration terminal is set to launch to the International Space Station to complete the space agency's first two-way laser communication relay system.
SpaceX counters FAA claims that its reentering Starlink satellites could hurt or kill people
SpaceX has asked the U.S. Federal Aviation Administration to correct a report warning that components from reentering Starlink constellation satellites could injure or even kill people on the ground.
Thanks to a layer of molten rock, Mars' core appears bigger than it is
Scientists have wondered why Mars' core can be so big and light at the same time. Two new studies might have an explanation.
Webb's first detection of heavy element from star merger
Under what conditions many chemical elements are created in the Universe has long been shrouded in mystery. This includes elements that are highly valuable, or even vital to life as we know it. Astronomers are now one step closer to an answer thanks to the James Webb Space Telescope and a high-energy event: the second-brightest gamma-ray burst ever detected, most likely caused by the merging of two neutron stars – which resulted in an explosion known as a kilonova.
SpaceX fuels up Starship in key test ahead of 2nd-ever flight (video, photos)
SpaceX loaded its latest Starship prototype with supercold propellant on Tuesday (Oct. 24), notching a key milestone ahead of the vehicle's upcoming test flight.

Cosmonauts will hunt for source of ISS leak during a spacewalk today. Watch it live
Two Russian cosmonauts will go outside the International Space Station today (Oct. 25) to investigate the source of a coolant leak that sprang up on Oct. 9. You can watch the webcast live.
Curiosity rover discovers new evidence Mars once had 'right conditions' for life
Thanks to NASA's Curiosity Mars rover, geologists have discovered evidence for ancient rivers on the Red Planet hiding in plain sight, suggesting the planet once had the right conditions for life.
James Webb Space Telescope photos to feature on US Priority Mail stamps in 2024
The U.S. Postal Service is granting priority status to the James Webb Space Telescope with two 2024 Priority Mail postage stamps, each featuring a cosmic image captured by the deep-space observatory.
Open doors for the ESA-ESTEC Open Day
Video: 00:03:03
On Saturday 7 and Sunday 8 October 2023, the European Space Agency opened the doors to the European Space Research and Technology Centre, ESTEC, in the Netherlands. Where science meets science fiction, the theme of this year's open day was ‘Science Fiction Gets Real’, highlighting how science fiction has inspired scientists and engineers to join ESA, and turn once imaginary concepts into science fact. The single largest ESA establishment invited the public to meet astronauts, view spacecraft, and peer behind the scenes of Europe’s space adventure, along with a full schedule of events and talks from Space Rocks, celebrating the art and culture of science and space.
