The mysterious star that was found to be dimming in 2015 (prompting speculation about an alien megastucture) has been spotted dimming again! The post The Star That Probably Doesn’t Have an Alien Megastructure (But Maybe it Does) is Dimming Again app

Astronomers have uncovered a moon orbiting the third largest dwarf planet, 2007 OR10, in the frigid outskirts of our solar system called the Kuiper Belt.

(Phys.org)An international team of astronomers led by Eike W. Guenther of the Thuringian State Observatory in Tautenburg, Germany, has characterized two "super-Earth" exoplanets orbiting a distant star designated K2-106, determining their size, mass and d

Scientist play a bit of fantasy exoplanet with Proxima b

An asteroid passed close to Earth this week only 12 days after it was discovered,

(Phys.org)An international team of space researchers has reported on the detection of a new fast radio burst (FRB) and their efforts to trace its source. They have written a paper describing the detection and search for evidence, and have uploaded it to t

Some astronauts may spend a year orbiting cislunar space before NASA finally makes its way to Mars. At the Human to Mars Summit in Washington DC, Greg Williams from the agency's human exploration division revealed the details of NASA's two-phase

Radiation exposure is among the top health risks for Mars astronauts, but the Red Planet poses many other dangers as well. Here are the fastest ways Mars would kill an unprotected traveler.

"Most planetary systems are like bands of amateur musicians playing their parts at different speeds," says Matt Russo, at the Canadian Institute for Theoretical Astrophysics (CITA). "TRAPPIST-1 is different; it's a super-group with all

The Kepler space telescope, NASA's dedicated exoplanet hunter, has provided a new look at a world close to home: the gas giant Neptune.

While we're searching the Universe for evidence of life, we should consider places in our own Solar System where ancient civilizations might have left an impact. The post Where Should We Look For Ancient Civilizations in the Solar System? appeared first o

Scientists have confirmed a nearby star's planetary system contains separate belts of asteroids, similar to our own solar system. The star is also about one-fifth the age of our sun. All that makes this star a good model of the early days of our solar sys

Combining data from NASA's Chandra X-ray Observatory with radio observations and computer simulations, an international team of scientists has discovered a 200,000-light-year wave of hot gas in the Perseus galaxy cluster.

Scientists have discovered a new planet with the mass of Earth, orbiting its star at the same distance that we orbit our sun. The planet is likely far too cold to be habitable for life as we know it, however, because its star is so faint. But the discover

If a migrating exoplanet dragged a Europa-like moon closer to its host star, the moons icy shell could melt into liquid oceans and breathable air

NASA's Cassini spacecraft has had its last close brush with Saturn's hazy moon Titan and is now beginning its final set of 22 orbits around the ringed planet.

Donald Trump wants humans on Mars in the next three years. He is unsatisfied with Nasa's current plans to get humans on the Red Planet in the 2030s and wants people on Mars by the end of his first term, in three-and-a-half years. At a push, he wants

This illustration shows Cassini diving through geyser plumes on Saturn's the ocean world moon of Enceladus. NASA/JPL-CaltechThere was much excitement when NASA recently revealed new details about the oceans that lurk beneath the surface of Saturns ti

An international team of scientists has found another rocky planet (LHS 1140b) orbiting a nearby red dwarf star. And it looks to be our best bet to date for finding a habitable exoplanet. The post Is This The Exoplanet Where Life Will First Be Found? appe

Astronomers have successfully peered inside a black hole to take an image of its event horizon. What does this new development from the Event Horizon Telescope means in testing Albert Einstein's general theory of relativity?
