Astronomers obtained the first detailed face-on view of a gaseous disk feeding the growth of a massive baby star.

Two Supermassive Black Holes Are On A Collision Course

Two Supermassive Black Holes Are On A Collision Course

Each black hole's mass is more than 800 million times that of our sun. As the two gradually draw closer together in a death spiral, they will begin sending gravitational waves rippling through space-time.


Black Hole Brings Down Curtain On Jellyfish Galaxy's Star Turn

Black Hole Brings Down Curtain On Jellyfish Galaxy's Star Turn

The supermassive black hole at the centre of jellyfish galaxy JO201 is stripping away gas and throwing it out into space, accelerating suppression of star formation and effectively 'killing' the galaxy.


ALMA Finds The Earliest Example Of Merging Galaxies

Researchers using the radio telescope ALMA (Atacama Large Millimeter/submillimeter Array) observed signals of oxygen, carbon, and dust from a galaxy in the early Universe 13 billion years ago.


3 Sky Surveys Completed in Preparation for Dark Energy Spectroscopic Instrument

3 Sky Surveys Completed in Preparation for Dark Energy Spectroscopic Instrument Video in Story

It took three sky surveys -- conducted at telescopes in two continents, covering one-third of the visible sky, and requiring almost 1,000 observing nights -- to prepare for a new project that will create the largest 3D map of the universe's galaxies and glean new insights about the universe's accelerating expansion.


New Method May Resolve Difficulty in Measuring Universe's Expansion

New Method May Resolve Difficulty in Measuring Universe's Expansion

Astronomers using National Science Foundation (NSF) radio telescopes have demonstrated how a combination of gravitational-wave and radio observations, along with theoretical modeling, can turn the mergers of pairs of neutron stars into a "cosmic ruler" capable of measuring the expansion of the Universe and resolving an outstanding question over its rate.

Hubble Watches Stars in Bloom

Hubble Watches Stars in Bloom

This NASA/ESA Hubble Space Telescope image shows bright, colorful pockets of star formation blooming like roses in a spiral galaxy named NGC 972.


Hubble Sets Sights on an Explosive Galaxy

Hubble Sets Sights on an Explosive Galaxy

When massive stars die at the end of their short lives, they light up the cosmos with bright, explosive bursts of light and material known as supernovae.


X-rays Spot Spinning Black Holes Across Cosmic Sea

X-rays Spot Spinning Black Holes Across Cosmic Sea

Like whirlpools in the ocean, spinning black holes in space create a swirling torrent around them. However, black holes do not create eddies of wind or water. Rather, they generate disks of gas and dust heated to hundreds of millions of degrees that glow in X-ray light.


Fast Radio Burst Pinpointed To Distant Galaxy

Fast Radio Burst Pinpointed To Distant Galaxy

Fast radio bursts (FRBs) are among the most enigmatic and powerful events in the cosmos.


Spiraling Filaments Feed Young Galaxies

Spiraling Filaments Feed Young Galaxies

Galaxies grow by accumulating gas from their surroundings and converting it to stars, but the details of this process have remained murky.


Hubble Captures Galaxy's Biggest Ongoing Stellar Fireworks Show

Hubble Captures Galaxy's Biggest Ongoing Stellar Fireworks Show

Imagine slow-motion fireworks that started exploding 170 years ago and are still continuing.


Hubble Captures Elusive, Irregular Galaxy

Hubble Captures Elusive, Irregular Galaxy

This image shows an irregular galaxy named IC 10, a member of the Local Group -- a collection of over 50 galaxies in our cosmic neighborhood that includes the Milky Way.


First Detection of Polarized Radio Waves in Gamma Ray Burst Jets

First Detection of Polarized Radio Waves in Gamma Ray Burst Jets

Good fortune and cutting-edge scientific equipment have allowed scientists to observe a Gamma Ray Burst jet with a radio telescope and detect the polarisation of radio waves within it for the first time - moving us closer to an understanding of what causes the universe's most powerful explosions.


Does the Gas in Galaxy Clusters Flow Like Honey?

Does the Gas in Galaxy Clusters Flow Like Honey?

We have seen intricate patterns that milk makes in coffee and much smoother ones that honey makes when stirred with a spoon. Which of these cases best describes the behavior of the hot gas in galaxy clusters?


Missing Matter And The Workings of The Galactic Ecosystem

Missing Matter And The Workings of The Galactic Ecosystem

Take a look at any galaxy in the universe through a telescope or in pictures captured by observatories and you might think you have a good idea of its shape.
