New study examines the links between science fiction and astronomy
"Today's science fiction is tomorrow's science fact." This quote, attributed to Isaac Asimov, captures science's intricate relationship with science fiction. And it is hardly a one-way relationship.

Can meteor showers be dangerous to spacecraft?
We've all read the advice that during a meteor shower there is no equipment needed. All you need to do is lay back and wonder at one of the most spectacular sights the universe has to offer. That's about it though and while you lay back on a lounger and watch, it really can be a wonderfully...

Are Andromeda and the Milky Way doomed to collide? Maybe not
Scientists discovered the Andromeda galaxy, known as M31, hundreds of years ago, and around a century ago, we realized that it had negative radial velocity toward the Milky Way. In other words, eventually, the two galaxies would merge spectacularly. That has been common knowledge for astronomers...

Good thing we found this Earth-sized planet now—it's about to be destroyed
Astronomers have confirmed the existence of exoplanets with extremely small orbits around their stars. But what about exoplanets that get close enough to be devoured by their star, and what if it's an Earth-sized exoplanet?

Scientists pinpoint dino-killing asteroid's origin: past Jupiter
An intense debate surrounding the cosmic rock that killed the dinosaurs has stirred scientists for decades, but a new study has revealed some important—and far-out—data about the impactor's origin story.

Researchers develop a test bed for separating valuable material on the moon
It's often better to flesh out technologies fully on Earth's surface before they're used in space. That is doubly true if that technology is part of the critical infrastructure keeping astronauts alive on the moon.

What time is it on the moon? Researchers develop a plan for precise timekeeping
For decades, the moon's subtle gravitational pull has posed a vexing challenge—atomic clocks on its surface would tick faster than those on Earth by about 56 microseconds per day. This extremely small difference doesn't seem like much, but it could disrupt the precise timing needed for important...

International astronomy group joins calls for a lunar clock to keep time on the moon
Time moves a tad faster on the moon. Now an international group of astronomers has joined calls to give the moon its own clock so that future space missions can keep track of minutes on the celestial body.

Scientist performs the first nonlinear study of black hole mimickers
In recent research, a scientist from Princeton University has performed the first nonlinear study of the merger of a black hole mimicker, aiming to understand the nature of gravitational wave signals emitted by these objects, which could potentially help to identify black holes more accurately.

NASA telescopes work out black hole's feeding schedule
By using new data from NASA's Chandra X-ray Observatory and Neil Gehrels Swift Observatory as well as ESA's XMM-Newton, a team of researchers has made important headway in understanding how—and when—a supermassive black hole obtains and then consumes material.

A galactic 'comet' called Terzan 5 illuminates a 100-year-old puzzle about cosmic rays
When my colleagues and I set to work on a century-old cosmic mystery, we found an unexpected celestial laboratory in Terzan 5, a dense star cluster currently plunging through our galaxy at breakneck speed.

Novel anemometer tracks sound travel for speedier, more precise wind speed calculations on Mars
Mars has a notoriously inhospitable environment, with temperatures that fluctuate dramatically over the course of a Martian day and average minus 80 degrees Fahrenheit. Its surface is mostly covered in red dust, with terrain typified by craters, canyons, and volcanoes. And its atmosphere is...

Scientists find oceans of water on Mars. It's just too deep to tap.
Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water—enough to fill oceans on the planet's surface.

Research team releases a 76 m-per-pixel global color image dataset and map of Mars
Remote-sensing images of Mars contain rich information about its surface morphology, topography, and geological structure. These data are fundamental for scientific research and exploration missions of Mars. Prior to China's first Mars exploration mission, data from six advanced optical imaging...

Study reports dim odds for finding alien civilizations
Are there any advanced alien civilizations elsewhere in our galaxy? We don't know. All we do know is that there is at least one. Should we be optimistic or pessimistic about finding others?
