The Universe

Scientists are currently unable to explain these mysteries, but are working hard to unravel them.

Studying the conditions of galaxies helps scientists to solve the mysteries of how stars, planets, and life evolved.

The new research suggests a modified theory of gravity that can explain the large-scale structure of the Universe.

The Hubble telescope has found that star formation happens in sudden bursts giving clues about the Universe's bumpy start.

"There are likely more weird ones out there, and we need to think about how to look for them," said Davy Kirkpatrick, an author of the study.

"We had never seen anything like it before, and we had no idea what they were," said astrophysicist Ray Norris.

The galaxies are located approximately 763 million light-years away in the constellation of Lynx.

Three astrophotographers share their top tips for taking beautiful images.

NASA still isn't sure what's wrong with the orbiting telescope, but engineers are being careful not to rush things, in case it leads to more issues.

Scientists spotted the star being ripped apart by a black hole millions of light-years from Earth.

"Too much excitement!" wrote one Twitter user in reference to the upcoming announcement.

Supernovae are cataclysmic explosions that occur during the last evolutionary stages in the life of massive stars.

Astronomers detected rare and never-before-seen structures in the galaxy's magnetic field including a helix-shaped featured and two vast "superbubbles."

"This all-sky image completely changes the way we look at the energetic universe," said researcher Peter Predehl.

"It's incredible to be able to make these kinds of discoveries," said researcher David Armstrong.

"The flash was so powerful that it lit up the stream like a Christmas tree," said researcher Andrew Fox.

Superflares are explosions up to 10,000 times more energetic than the typical solar flares that our sun produces.

The black hole forms part of a triple star system known as HR 6819, which can be seen without binoculars or telescopes from the southern hemisphere on a dark, clear night.

The map was put together using six regional maps made during the Apollo era, in combination with information collected during recent lunar missions.

"This is comparable to several musicians beating distinct rhythms, yet who beat at the same time at the beginning of each bar," said researcher Nathan Hara.

"I think you can make an argument that it's the greatest scientific instrument ever built," Mike Massimino told Newsweek.

"While we have long been able to directly probe the winds of the bodies in our own solar system, we've had to conjecture what they're like in other kinds of bodies," researcher Peter Williams said.

NGC 4651 is sometimes referred to as the "Umbrella Galaxy" due to a faint umbrella-shaped structure that surrounds it.

Researchers identified the minor planets beyond the orbit of Neptune.

Temperatures on the day side of the planet—which perpetually faces its star—are hot enough to vaporize iron.

The star appears to have formed by the merging of two smaller white dwarfs.

"We've seen outbursts in the centers of galaxies before, but this one is really, really massive," researcher Melanie Johnston-Hollitt said.

"There is a reasonable chance that the planet hosts a large ocean underneath the atmosphere at pressures and temperatures similar to those in the Earth's oceans," researcher Nikku Madhusudhan said.

The hourglass-shaped object, known as CVMP 1, is one of the largest known planetary nebulae.

Scientists previously thought stars like these were not capable of such high-energy eruptions.
