Supernova sends "cannonball" pulsar hurtling at intergalactic speeds

Michael Irving March 19, 2019

The universe is full of fascinating stories, and NASA’s Fermi Gamma-ray Space Telescope has just spotted a doozy. About 10,000 years ago a star went supernova, and the explosion shot the resulting pulsar off like a cannonball, with enough force to send it hurtling out of the galaxy altogether.

Astronomers spot a new planetary system forming nearby

Michael Irving March 17, 2019

Roughly 4.6 billion years ago, all the planets in our solar system began to form in a huge disk of dust and gas that swirled around the Sun. Now astronomers have spotted the same kind of thing happening around a nearby young star, which could give us a better understanding of planet formation.

NASA lab brews up alien atmospheres here on Earth

Michael Irving March 14, 2019

Earth’s pleasant, life-giving atmosphere is turning out to be somewhat of an oddity. To get a better understanding of exoplanets, a team at NASA’s Jet Propulsion Laboratory (JPL) has recreated one of these alien atmospheres in the lab.

Massive hypervelocity star escaping Milky Way hints at presence of hidden black hole

Anthony Wood March 13, 2019

A team of astronomers has managed to find the origin of an enormous star that is currently barreling out of the Milky Way having escaped from one of our galaxy’s spiral arms. The discovery challenges the theory that such stars come from the galactic center.

Astronomers calculate the mass of the entire Milky Way galaxy

Michael Irving March 7, 2019

How heavy is the Milky Way galaxy? A team of astronomers has used data from Hubble and the Gaia satellite to make the most accurate measurement of the mass of the galaxy by studying the motions of star clusters orbiting the Milky Way.

NASA's newest mission to look for life's ingredients and probe the universe's deep past

Michael Irving February 13, 2019

NASA has selected the newest space mission for its Explorer program: the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx). The spacecraft will search for the ingredients of life in the Milky Way, and peer as far as 10 billion years back in time.

The Milky Way galaxy is warped, according to new 3D map

Michael Irving February 4, 2019

Conventional wisdom has long held that the Milky Way was a flat disk of stars and gas, with a bulge in the middle. But now astronomers have created a more accurate 3D map of the galaxy and found that it’s more warped and twisted than previously thought.

Hubble captures "lost light" to reveal deepest look into the universe yet

Michael Irving January 24, 2019

Astronomers from the Instituto de Astrofísica de Canarias (IAC) have re-processed an old Hubble Ultra-Deep Field (HUDF) image to find new details. The end result is the deepest image ever taken of the universe from space.

The new Hubble Ultra Deep Field image reveals new details, thanks to the recovery of "lost ...
