NASA’s Hubble Telescope Found the Galaxy Far, Far, Farthest Away!

space-newsCan you feel that? I think my nerdy little heart just skipped a beat. 😍

A group of international astronomers have pushed NASA’s Hubble Space Telescope to its limits. As a result, they’ve smashed records by measuring the furthest galaxy ever seen in the universe! Bye, bye, cosmic distance record. Hello GN-z11!

This surprisingly bright infant galaxy, named GN-z11, is seen as it was 13.4 billion years in the past, just 400 million years after the Big Bang.


“We’ve taken a major step back in time, beyond what we’d ever expected to be able to do with Hubble. We see GN-z11 at a time when the universe was only three percent of its current age,” explained principal investigator Pascal Oesch of Yale University.

Astronomers are closing in on the first galaxies that formed in the universe. The new Hubble observations take astronomers into a realm that was once thought to be only reachable with NASA’s upcoming James Webb Space Telescope.

Space Photos: NASA’s Hubble Turns the Universe into Eye Candy

space-newsHow incredible is this photo?? This galaxy is the universe’s version of a hot mess. Roughly a quarter of galaxies don’t take on any recognizable shape; they are known as irregular galaxies. Most galaxies rock a crazy spiral or elliptical structure – but not NGC 5408, which is located about 16 million light-years from Earth in the constellation of Centaurus (The Centaur).

Known as irregular galaxies, this group includes NGC 5408, the galaxy that has been snapped here by the NASA/ESA Hubble Space Telescope.

The photo above was taken by NASA’s Hubble Space Telescope. Launched in 1990, Hubble has traveled over 3 billion miles around Earth, made 1.2 million observations, and snapped pics of locations more than 13.4 billion light years from our planet. I’ve collected a few amazing photos taken by Hubble. Enjoy! ✨





NASA Names Massive Strange Star in the Milky Way Something ‘NASTY’

Krystian Science SpaceAstonomers using NASA’s Hubble Space Telescope have discovered surprising new information regarding a massive, one-of-a-kind star, whose behavior has never been seen before in our Milky Way galaxy. The star’s new nickname, ‘Nasty 1,’ is a play on its official catalog name, ‘NaSt1’ – because the rapidly aging star is just that weird.

Nasty 1 was originally identified as a Wolf-Rayet star when it was first discovered several decades ago. Wolf-Rayet stars are incredibly hot, massive stars (20x larger than our sun) with a high rate of mass loss – some believe they represent a final burst of activity before a huge star begins to die.

The thing is, Nasty 1 doesn’t look like your usual Word-Rayet star. Astronomers expected to see twin lobes of gas flowing from opposite sides of the star. Instead, they saw a pancake shaped disc of gas encircling the star that is nearly 2 trillion miles wide! This disc could be the result of a binary interaction – which there are very few examples of in the galaxy because this phase is so short-lived.

The Team’s Scenario: A massive star evolves very quickly, and as it begins to run out of hydrogen, it swells up. Its outer hydrogen envelope becomes more loosely bound and vulnerable to gravitational stripping, or a type of stellar cannibalism, by a nearby companion star. In that process, the more compact companion star winds up gaining mass, and the original massive star loses its hydrogen envelope, exposing its helium core to become a Wolf-Rayet star.

But the mass transfer process in mammoth binary systems isn’t always efficient. Some of the stripped matter can spill out during the gravitational tussle between the stars, creating a disk around the binary.

“That’s what we think is happening in Nasty 1,” Mauerhan said. “We think there is a Wolf-Rayet star buried inside the nebula, and we think the nebula is being created by this mass-transfer process. So this type of sloppy stellar cannibalism actually makes Nasty 1 a rather fitting nickname… what evolutionary path the star will take is uncertain, but it will definitely not be boring”

The team’s results will appear May 21 in the online edition of the Monthly Notices of the Royal Astronomical Society.
