Oddly behaving star reveals a black hole hiding in a globular cluster, a first

The word globule isn’t the most appealing term. Maybe this is why globular clusters don’t get as much press as they deserve. These dense collections of ancient stars numbering in the tens of thousands are home to some of the oldest stars ...

Counting starspots

Small dark regions on the Sun have helped solar scientists learn more about our closest star for centuries. But while picking out sunspots is reasonably easy on our Sun, identifying them on Sun-like stars lying light-years away can be a challenge. No...

A black hole’s “double burp” shows its behavior over time

Supermassive black holes reside at the center of most, if not all, massive (and possibly low-mass) galaxies. They range in size from millions to billions of solar masses, and they can eat voraciously or not at all, depending on their surroundings. Bu...

Future spacecraft can use pulsars to navigate completely autonomously

Although it’s possible for space missions to communicate data with Earth, the process is anything but fast. Voyager 1, for example, takes about 19 hours to send a signal back to Earth, and that lag only increases as the spacecraft gets further ...

NASA images the most distant galaxy ever resolved

With the help of advanced telescopes and gravitational glasses, NASA captured an image of SPT0615-JD, the most distant galaxy ever caught on camera. This ancient galaxy was already around when the infant universe was just 500 million years old. Altho...

Massive, deep deposits of ice found on Mars

Despite the fact that Mars has an atmosphere just 1% as dense as Earth’s, the surface of the Red Planet still has to deal with plenty of weathering and erosion. In 2008, researchers even captured a full-scale avalanche on Mars as it plunged dow...

NASA’s Alaskan rockets to study galactic X-rays emission and more

University researchers and NASA scientists will soon head to Alaska’s Poker Flat Research Range (PFRR) to launch a series of four rockets designed to measure space’s X-ray emissions and to study how our upper atmosphere is impacted by add...

Space causes astronauts to run hot

A great amount of time and effort is spent ensuring the mental and physical well-being of astronauts aboard the International Space Station (ISS), and new research shows that increased body temperature is another factor to consider when evaluating as...

Obese stars are more common than expected

According to a study published today in the journal Science, the universe is teeming with many more massive stars than astronomers previously thought. Since massive stars play a crucial role in shaping our universe — through stellar winds, supe...

Astronomers are one step closer to unlocking the mystery of Tabby’s Star

Tabby’s Star — the informal name for the star KIC 8462852 — has been popping up in astronomical news for quite some time now. This famously and mysteriously dimming star has been the subject of extensive observations and extreme spe...

DNA of unknown microbes sequenced in space for the first time

In July 2016, while aboard the International Space Station (ISS), NASA astronaut Kate Rubins successfully sequenced mouse DNA that was delivered to her from Earth. This made Rubins the first person ever to identify an organism’s DNA while worki...
