The Dark Energy Camera's New Image is Reminiscent of van Gogh

The Dark Energy Camera (DECam) has a massive 570 megapixel camera, and its new image is of the Corona Australis Molecular Cloud. Corona Australis is one of the closest star-forming regions to Earth. It's not as well-studied as the Orion Molecular Cloud or Ophiuchus, but as DECam's new iage of Corona Australis shows, it's just as fascinating.

What's It Like to Travel Near the Speed of Light? Part 4: The Hot View

An accelerating observer finds their empty vacuum glowing with real particles, a bizarre effect called Unruh radiation. It's a cousin to Hawking radiation, but with no black hole required, just a rocket and its throttle.

The Roman Space Telescope Will Find Ancient Black Holes By Watching How They Eat Stars

When supermassive black holes (SMBH) in a certain mass range eat a star, they first tear it apart in a Tidal Disruption Event (TDE). By detecting TDE across cosmic time, astronomers can chart the growth of SMBH as the Universe aged. The Nancy Grace Roman Space Telescope will help, by finding about 100 TDEs every year.

Scientists are Teaching Shrimp to Eat in Microgravity for Future Moon Bases

As far as we know, food doesn?t exist naturally in space. We have to bring it with us if we want to explore the final frontier. One of the oldest and most common types of food on planet Earth is seafood, yet we know surprisingly little about how aquatic animals would react to the microgravity environment they would experience in space. A new paper by researchers at Japan?s Okayama University of Science, which was recently published in Microgravity Science and Technology, hopes to tackle that question. It used a novel way to simulate microgravity to watch how crustaceans would react to the space environment, and found that they could likely be good candidates as part of a future space food chain.

What's It Like to Travel Near the Speed of Light? Part 3: The Limited View

Constant acceleration builds a horizon out of nothing but motion, walling off part of the universe forever. Meet Wolfgang Rindler, the coffee date you'll never reach, and the light that can chase you for infinite time without ever catching up.

X-Ray Eyes Reveal the Magnetic Secrets of the Lighthouse Pulsar's Cosmic Wake

Occasionally, when a massive star dies in a supernova, it can leave behind a dense, rapidly spinning core known as a pulsar. These extreme objects are some of the most fascinating in the universe, and are extremely useful for astronomers when measuring distances or navigating the void of space. A new paper from Jack Dinsmore, a graduate student at Stanford, and his co-authors, and published in The Astrophysical Journal, takes a look at some of the features of one of the most famous examples of a pulsar - PSR J1101-6101, commonly known as the Lighthouse pulsar.

FCC Approves First Launch for Space Reflector Constellation

The United States Federal Communications Commission (FCC) recently approved the first test launch of Reflect Orbital?s E�rendil-1 satellite. Sporting an 18 by 18 meter-wide reflector once unfurled, the satellite will test the ability to reflect sunlight back to Earth, on demand. The company envisions more than 50,000 reflectors girding the Earth in low Earth orbit by 2035, while many in the astronomical community have raised concerns on the project's impact.

Satellite Images of Pengiun Poo Reveal Climate Change's Impact on the Species

Researchers utilized 30 years of Landsat satellite imagery to analyze the color and spectral signatures of Ad�lie penguin guano across Antarctica, marking the first time space-based observations have captured food-web and population dynamics at a continental scale.

This Exoplanet Hid for 10 Years Before Astronomers Finally Found It

A team of astronomers have discovered a third planet orbiting the star Beta Pictoris. The new planet, Beta Pictoris d, is 100 times fainter than Beta Pictoris b ? the first planet discovered in the same system ? and is among the lightest exoplanets ever to be imaged from the ground. After spotting the planet using the European Southern Observatory?s Very Large Telescope (ESO?s VLT), the team found it had been hiding in archive observations spanning more than a decade.

What's It Like to Travel Near the Speed of Light? Part 2: The Warped View

Move fast enough and the entire universe compresses into a searing, blueshifted cone of light aimed at your face. How relativistic aberration and the Doppler effect warp your view of the cosmos as you approach lightspeed.
