New observations suggest that the universe’s oldest galaxies are brighter than expected. Here's why this may be a big deal.
In a distant corner of the cosmos, some ancient galaxies are challenging our grasp of cosmic history.
Young galaxies such as this should have been "small and messy looking."
The galaxy has several “layers” that astronomers have imaged using a phenomenon called gravitation lensing.
We may all be aliens.
A new view of the Milky Way sees through neutrinos.
Although they can contain billions of stars, dwarf galaxies are nevertheless just a fraction of the size of Milky Way.
The telescope is already making incredible discoveries just one week after its debut image.
The European Space Agency released its treasure trove of stars.
HD1 bests the rest.
Hubble may have spotted a very rare phenomenon.
Black holes may do more than just destroy -- they may also create new things.
This will teach us a lot about how the element forms in the Universe.
The subdued, mysterious, and longing tunes sound very appropriate for outer space.
A trifecta of recent discoveries has challenged models of galactic evolution, suggesting that galaxies could have formed much sooner in the Universe’s 13.7 billion year history than previously believed.
The halo surrounding the Milky Way may be much hotter than originally thought.
Things are pretty stressful on Earth right now -- so look at the sky!
A dim patch in an otherwise bright galaxy is the epicenter of a supermassive black hole whose mass is 40 billion times greater than that of the Sun.
This immense simulation is so complex that scientists have observed phenomena that had not been programmed explicitly in the code.
We still don't know what dark energy *is*, but we found out another thing it isn't.
The study might help scientists understand how galaxies evolve.
They were much brighter than they were supposed to be.
Torque is warping the galaxy's outer disk in an S-shape.
The galaxies date from the so-called cosmic Dark Ages.
The findings could topple our current understanding of how galaxies merge.
Talk about a big count!
It's quite possibly one of the most massive objects in the universe.
An incredibly fruitful mission sheds new secrets about the Milky Way.
Scientists are left in the dark again.
Looks like we can expect more gravitational waves in the near future.
Our galaxy still holds many secrets.
A new take on the whole 'twinkle twinkle' thing.
The elusive dark matter surprises us once again... this time by being absent.
Regardless of their size, all galaxies that just as long to come full circle.
It might teach us about how galaxies such as the Milky Way evolved.
It's supposed to be one of the first galaxies.
The Milky Way just got an ego boost.
Aside from the romantic aspect, the study also offers an important scientific perspective.
Sometimes, even a black hole can choke on its meal.
In the aftermath of a titanic galactic battle, a merged black hole caused some waves.
Surprisingly pure.
We may have dramatically underestimated what lies in the Universe.
Drawn by gravity, a dwarf galaxy pair is leaving the void for a more crowded region of the universe.
The findings could reveal the location of the missing matter of our universe.
A faint, blue galaxy 30 million light years away from Earth could help us understand the conditions from the birth of the Universe. Nicknamed "The Little Lion", the galaxy contains the lowest level of heavy chemical elements ever observed in a system of stars - meaning its make-up is similar to what was happening directly after Big Bang.
Astronomers have discovered a new species of galaxies in the cosmic wilderness.
Astronomers find the parent of an orphan planet. The finding makes the solar system the biggest in the galaxy.
The Milky Way has been around for at least 13.7 billion years, but it has its younger and older areas.
Astronomers have discovered a whopping 854 new ultra-dark galaxies which might have large quantities of the elusive dark matter, which makes out most of our universe.
There are two types of galaxies: 'alive' and 'dead' ones. Those galaxies that are still alive are called so because they still produce stars inside, while the dead ones are stripped and devoid of their stellar nurseries. In a case of forensic astronomy of the utmost importance, a team at the University of Cambridge and the Royal Observatory Edinburgh has revealed the leading cause of death for most deceased galaxies of average size: death by strangulation. What remains now is to identify the killer, the researchers say.
