What if we’re truly alone?

At least once, you’ve looked up at the night sky and asked the same longstanding question we’ve all asked at least once, “Are we alone?” With all those points of light out there, we can’t be the only intelligent beings in the universe, right? There must be at least one technological civilization aside from us …

Astronomers Detect the Faint Glow of Stars in Between Galaxies

Not all stars are members of galaxies. Some stars exist in the space between galaxies, though they didn’t form there. They’re called intra-group stars, and astronomers study them by observing their light, called intra-group light (IGL.) They’re challenging to observe because their light is extremely faint and overpowered by the light of nearby galaxies. Astronomers …

Astronomers Directly Image a Jupiter-Sized Planet Orbiting a Sunlike Star

According to the most widely-accepted theory, planetary systems form from large clouds of dust and gas that form disks around young stars. Over time, these disks accrete to create planets of varying size, composition, and distance from their parent star. In the past few decades, observations in the mid- and far-infrared wavelengths have led to …

Quasars Produce Giant Jets That Focus Like Lasers. Why They Focus is Still a Mystery, but it’s not Coming From the Galaxy Itself

New technologies bring new astronomical insights, which is especially satisfying when they help answer debates that have been ongoing for decades. One of those debates is why exactly the plasma emitted from pulsars “collimates” or is brought together in a narrow beam. While it doesn’t provide a definitive answer to that question, a new paper …

Baby Gas Giants Cast Shadows on Their Siblings

A team of astronomers has caught glimpses of gas giants forming around a very young star. The nascent giants are having a chilling effect on their potential siblings. Planet formation takes place inside an almost impenetrable veil of dust. As our telescopes and instruments become more capable, we’re getting better looks at the process. Much …

The Technique for Detecting Meteors Could be Used to Find Dark Matter Particles Entering the Atmosphere

Researchers from Ohio State University have come up with a novel method to detect dark matter, based on existing meteor-detecting technology. By using ground-based radar to search for ionization trails, similar to those produced by meteors as they streak through the air, they hope to use the Earth’s atmosphere as a super-sized particle detector. The …

The Second-Closest Supermassive Black Hole Might be in a Nearby Dwarf Galaxy

There’s a little galaxy in the Milky Way’s cosmic neighborhood called Leo 1. It’s a dwarf spheroidal that lies less than a million light-years away from us. Surprisingly, it has a supermassive black hole about the same mass as Sagittarius A* in our galaxy. That’s unusual in several ways, and astronomers want to know more …
