Astronomers Detect Rare ‘Missing Link’ Black Hole in Our Closest Galactic Neighbor

A rare treasure that could shed light on the evolution of black holes has been discovered in the Milky Way’s closest large galactic neighbor. In a cluster of stars in the Andromeda galaxy, aka M31, astronomers studied changes in light to identify a black hole clocking in at almost 100,000 times the mass of the … Read more

Famous astronomers: How these scientists shaped astronomy

Throughout human history, astronomers have helped people understand what they see in the night sky. These famous astronomers — many of them great scientists who mastered many fields — explained space phenomena with varying degrees of accuracy.  Over the centuries, a geocentric view of the universe — with Earth at the center of everything — … Read more

Astronomers Have Identified a New Kind of Supernova We Never Knew Existed

We often think of supernova explosions as inevitable for large stars. Big star runs out of fuel, gravity collapses its core, and BOOM! But astronomers have long thought at least one type of large star didn’t end with a supernova. Known as Wolf-Rayet stars, they were thought to end with a quiet collapse of their core … Read more

SpaceX Satellites Have Invaded Astronomers’ Views of The Sky, And It’s Getting Worse

With the rapid expansion of commercial space, there is a growing number of satellites in orbit around our planet. Most of these are in low-Earth orbit, which is becoming increasingly crowded.   This has led some to be concerned about a catastrophic rise of space debris, as well as a growing frustration by astronomers due … Read more

Astronomers propose building a neutrino telescope — out of the Pacific Ocean

Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of “Ask a Spaceman” and “Space Radio,” and author of “How to Die in Space.” Sutter contributed this article to Space.com’s Expert Voices: Op-Ed & Insights. Neutrinos are one of the most elusive particles in the cosmos, second only to … Read more

For The First Time, Astronomers Detect Rugby-Ball Shape of a Deformed Exoplanet

Beyond the Solar System, out there in the wider galaxy, a very strange subset of exoplanets exists. Called hot Jupiters, these are majorly clingy – hugging so close to their host stars, they’re not just intensely hot, but also likely warped by gravitational forces.   Now, for the first time, astronomers have actually detected the … Read more

Strange and hidden Jupiter-size exoplanet spotted by astronomers and citizen scientists

A group of astronomers and citizen scientists has uncovered a hidden planet the size of Jupiter in a distant solar system, and they should get the chance to see it again soon. The planet, designated TOI-2180 b, is relatively close to us here on Earth, at only 379 light-years away. But what makes this world … Read more

Astronomers Detect Water Vapor in The Atmosphere of a ‘Super Neptune’ Exoplanet

New Year’s Day comes around once every 47.5 hours on the roughly Neptune-sized exoplanet TOI 674b, which makes it something of a rare creature.  In spite of years of hunting, surprisingly few middle-sized gas giants have ever been seen with orbits shorter than a few days in length, creating what astronomers refer to as a … Read more

Astronomers Have Found Another Possible ‘Exomoon’ beyond Our Solar System

And then there were two—maybe. Astronomers say they have found a second plausible candidate for a moon beyond our solar system, an exomoon, orbiting a world nearly 6,000 light-years from Earth. Called Kepler-1708 b-i, the moon appears to be a gas-dominated object, slightly smaller than Neptune, orbiting a Jupiter-sized planet around a sunlike star—an unusual … Read more

New Breakthrough Lets Scientists Track Mysterious Fast Radio Bursts in Real-Time

Located in the Okanagan Valley outside of Penticton, British Columbia, there is a massive radio observatory dedicated to observing cosmic radio phenomena. It’s called the Canadian Hydrogen Intensity Mapping Experiment (CHIME), a cylindrical parabolic radio telescope that looks like what snowboarders would call a “half-pipe”. This array is part of the Dominion Radio Astrophysical Observatory … Read more
