SPACE

A supermassive black hole is the farthest one scientists have ever found, but it is so large and old that astronomers don’t know what to make of it.

To withstand the harsh conditions of space, which are very different from Earth, the space telescope is being put through a large number of tests for its hardiness.

The accidental discovery was made while scientists were trying to determine if K2-18b is a larger version of Earth or a scaled-down version of Neptune.

NASA fired up some old thrusters on the back of the Voyager 1 space probe for the first time in 1980. Despite a 37 year gap between uses, the thrusters work perfectly.

The Juno craft has been orbiting Jupiter for more than a year now and it's taken some incredible photos of the giant.

Black holes are formed when stars collapse, or when neutron stars merge. But some theories hypothesize black holes existed even before stars had formed in the universe.

Subsurface oceans on icy bodies in the outer solar system, beyond Neptune’s orbit, could exist because of their interaction with their moons, including on Pluto.

Detection of the distant binary system was almost a surprise finding. The black holes, with about 200 million solar masses combined, photobombed images of the nearby Andromeda galaxy.

Australia is playing a major role in developing legal guidelines that would govern how any war in space is played out. The authors of MILAMOS hope the manual is never actually required.

Given the possible patterns of how air flows on some potentially Earth-like exoplanets, it may be that signs of life exist along or close to their equators.

It has seven new instruments and different scientific objectives, but NASA’s upcoming mission to Mars is also similar to its predecessor in many ways.

Having discovered an asteroid from outside the solar system for the first time, scientists are hoping there are more out there – illuminating the path to extrasolar worlds.

Russian cosmonaut Anton Shkaplerov said the bacteria on the International Space Station did not appear to be from Earth.

The data was collected by Hubble Space Telescope and the Gaia satellite, and it also questions the standard model predictions of dark matter halos around galaxies.

Scientists have combined data from 16 separate NASA and Los Alamos National Laboratory (LANL) spacecraft to observe a possible never-seen-before particle phenomenon in the magnetic environment around us that could help understanding Earth's magnetosphere.

Two young earthworm offspring were found in an experiment that uses NASA-provided Mars-like soil to grow plants that could aid human survival outside Earth.

An asteroid considered "potentially hazardous" by NASA is set to skim the Earth’s atmosphere just days before Christmas.

A flat-Earth believer will blast himself into the skies on Saturday in self-made rocket to prove the planet is not round. Here's how to watch the event live.

UFO Stalker, a website that maps UFO encounters worldwide, has reported that 83,715 UFO sightings were reported this year.

A new method of measurement is modeled on thermonuclear explosions on the surface of the stars, which are the second-most dense objects known in the universe.

These two mysterious entities are together thought to account for over 95 percent of all energy in the observable universe, and are largely accepted as real in the astronomy community.
