Although the universe started out with a bang it quickly evolved to a relatively cool, dark place. After a few hundred thousand years the lights came back on and scientists are still trying to figure out why.
A rare triple-star system surrounded by a disk with a spiral structure has been discovered by a University of Oklahoma-led research team.
Since Edwin Hubble discovered that the Milky Way is not the only galaxy in the Universe astronomers try to find out how many of them are there. This new Hubblecast focusses on the question "How many galaxies are there?" including the new numbers achieved in 2016.
The two most powerful optical/IR telescopes in history -- NASA's Hubble and James Webb Space Telescopes -- will be in space at the same time.
Matters of the heart can be puzzling and mysterious -- so too with unusual astronomical objects called heartbeat stars.
Astronomers have found a pair of extraordinary cosmic objects that dramatically burst in X-rays. This discovery, obtained with NASA's Chandra X-ray Observatory and ESA's XMM-Newton observatory, may represent a new class of explosive events found in space.
Everything we know about the formation of solar systems might be wrong, says University of Florida astronomy professor Jian Ge and his postdoc, Bo Ma.
An international team of astronomers have used the Very Large Telescope Interferometer to image the Eta Carinae star system in the greatest detail ever achieved.
The astronomical images taken by Hubble are amongst the best known in the world. Behind these iconic observations stands a sophisticated instrument, based upon world-changing technology.
Each year, NASA's Chandra X-ray Observatory helps celebrate American Archive Month by releasing a collection of images using X-ray data in its archive.
This image, taken by the NASA/ESA Hubble Space Telescope's Wide Field Planetary Camera 2, shows a spiral galaxy named NGC 278.
Supermassive black holes more than a million times the mass of our sun exist at the centers of many galaxies, but how they came to be is unclear.
The universe suddenly looks a lot more crowded, thanks to a deep-sky census assembled from surveys taken by NASA's Hubble Space Telescope and other observatories.
Our Milky Way has a densely populated centre -- a feature common to many galaxies, but unique in that it is close enough to study in depth.
In August astronomers announced that the nearby star Proxima Centauri hosts an Earth-sized planet (called Proxima b) in its habitable zone.
The two spiral arms winding towards the bright centre might deceive you into thinking you are looking at a galaxy a bit like our Milky Way.
Great balls of fire! NASA's Hubble Space Telescope has detected superhot blobs of gas, each twice as massive as the planet Mars, being ejected near a dying star.
