The Hubble Space Telescope is an expert at imaging distant galaxies, bringing mysterious galactic features into the light. In the case of one particular elliptical galaxy, around 150 million light-years distant, Hubble has revealed a conundrum and a possible mechanism behind why some galaxies look so old. Continue reading Hubble Spies a Strange Old Dusty Galaxy
Just in time for Halloween, astronomers have announced the discovery of huge stars that spin so fast they start to resemble awesome stellar pumpkins. And these “pumpkin stars” are incredible X-ray generators, producing radiation hundreds of times more powerful than our sun. Continue reading ‘Pumpkin Stars’ Are All You Need for a Stellar Halloween
A giant blob of gas and dust far off in the universe mysteriously glows bright green, and astronomers have finally figured out why. Two huge galaxies were observed in the blob’s core, and they’re surrounded by a swarm of smaller galaxies in what appears to be the birth of a massive cluster of galaxies. Continue reading Monster Green Cosmic Blob Mystery Solved
A California man has come up with a unique way to mark the passage of time. While most of us think in terms of months (that were originally based on the movement of the moon) and years (which follow the Earth’s path around the sun), he decided to think even bigger. Continue reading ‘Galactic Tick Day’ Celebrates Our Trip Through the Galaxy
Using some of the planet’s most powerful telescopes, astronomers decided to zoom-in on the galactic oddity called Dragonfly 44 to find it wasn’t one of your run-of-the-mill galaxies, it is in fact a galaxy rammed full of material we can’t see. Continue reading Camouflaged Dark Matter Galaxy Discovered
The raw material to create stars for millions of years is captured in this stunning, newly retrieved photo from the European Space Agency’s Herschel Space Observatory.
The space-based telescope was built to detect radiation that had been invisible to other telescopes at the time. That ability not only allowed it to fulfill its major objective of discovering how the first galaxies formed and evolved, but also made it an excellent choice for detecting dust and gas clouds that lead to the formation of new stars. Although its mission ended in 2013, scientists are still analyzing the wealth of data that Herschel collected over its four years of operation, uncovering stunning photographs such as this one. Continue reading Enormous Stars Forming in the ‘Little Fox’ Captured in Stunning Photo
A collection of newfound galaxies is illuminating how the early universe broke free from its Dark Ages. The family of galaxies may have played a role in the shift from a time when some light could not penetrate to an era of a transparent universe. Continue reading The Universe’s First Galaxies May Light Up Its Dark Ages
Using the power of interferometry, two astronomical projects are, for the first time, close to directly observing the black hole in the center of the Milky Way. There’s a monster living in the center of the galaxy.
