CERN Adds a New Particle to Large Hadron Collider's Subatomic Zoo

Scientists at Europe's CERN research center say the Large Hadron Collider's LHCb experiment has discovered a "doubly charmed" particle that's like a proton, but four times as weighty.

Scientists Find Evidence of Worlds Colliding ... 11,000 Light-Years Away

Astronomers say unusual readings from a star system 11,000 light-years away suggest that two of the planets circling the star crashed into each other, creating a huge, light-obscuring cloud of rocks and dust.

Is the Universe Defective? Part 4: Hiding in Plain Darkness

The WHAT? Yeah, the vortons. It’s not an anime monster-hunting show. It’s not some AI startup company. It’s a…it’s a thing. I think.

New Study Complicates the Search for Alien Oxygen

Oxygen has been the most important gas in our search for life among the cosmos thus far. On Earth, we have it in abundance because it is produced by biological synthesis. But that might not be the case on other planets, so even if we do find a very clear high oxygen signal in the atmosphere of an exoplanet, it might not be a clear indication that life exists there. A new paper, available in pre-print on arXiv, from Margaret Turcotte Seavey and a team of researchers from institutions like the NASA Goddard Space Flight Center and Johns Hopkins University, adds some additional context to what else might be going on in those atmospheres. In particular, they note that if there’s even a little bit of water vapor, it can make a big difference in whether a lifeless rock looks like a living, thriving world.

The Coming Age of Space Stations

With the ISS set to retire in 2030, several plans are in place to replace it. These include existing space stations, proposals by rising national space agencies, and commercial space stations. With multiple outposts in orbit, the potential for research, development, and even conflict is considerable!

Are Rogue Exomoons the Newest Frontier in the Search for Habitability?

There may be as many rogue planets or free-floating planets in the Milky Way as there are stars. If there are billions of these worlds, some of them have likely held onto their moons. New research reveals a pathway to habitability for these rogue exomoons.

Microscopic "Ski-Jumps" Could Shrink Spacecraft LiDAR to the Size of a Microchip

Every ounce counts when launching a rocket, which is why considerations for the Size, Weight, and Power (SWaP) of every component matters so much. For decades, one of the heaviest and most power-hungry components on a spacecraft has been its optical and communications hardware - specifically the bulky mechanical mirror used for LiDAR and free-space laser communications. But a new paper, published in Nature by researchers at MIT, MITRE, and Sandia National Laboratories, might have just fundamentally changed the SWaP considerations of LiDAR systems. Their technology, which they’re called a “photonic ski-jump” could one day revolutionize how spacecraft communicate.
