Einstein Said It Would Never Be Seen. It Just Was

Astronomers observe gravitational microlensing between distant stars

(Newser) - Astronomers just proved the great Albert Einstein wrong—by proving him right. Einstein's 1915 theory of relativity says gravity can distort light and alter its path. National Geographic reports Einstein posited that would create a phenomenon called gravitational microlensing between two stars appearing to pass in front of each... More »

Universe Expanding Faster Than Thought

Surprise finding suggests Einstein was a little off

(Newser) - New calculations in the cosmos have revealed a surprise: The universe appears to be expanding faster than anyone thought. Using the Hubble Space Telescope, scientists measured the distance to stars in 19 galaxies and concluded that the universe is growing 5% to 9% quicker than expected, the researchers say in... More »

Hubble Spots 'Butterfly' 2K Light-Years Away

It's also known as the Twin Jet Nebula, and it's pretty

(Newser) - It's a bird, it's a plane, it's ... a space butterfly? That's essentially what the Hubble Space Telescope has captured in a new image of the Twin Jet Nebula, a shimmering planetary nebula that strongly resembles a winged insect, reports CNET . What you're actually seeing in... More »

The Hubble Spots 'Smiley Face' in Space

Its 'eyes' are actually galaxies

(Newser) - The universe is smiling down on us—almost literally. The Hubble Telescope has captured a "smiley face" in space: two bright yellow eyes (a cluster of galaxies called SDSS J1038+4849), a white nose, and a faint smile and incomplete circle around the entire face. But those curving lines "... More »

Astonishing NASA Image Captures Color of 10K Galaxies

Hubble shot spans light spectrum, took 841 orbits to create

(Newser) - Thousands of galaxies of all ages, shapes, and colors can be seen in a stunning new image from NASA's Hubble Space Telescope. Some of the oldest galaxies visible appear as light from nearly 12 billion years ago, almost as old as the universe, but NASA says the most exciting... More »

Jupiter's Great Red Spot Has Really Shrunk

It looks more like a circle than an oval

(Newser) - The signature red spot we see in pictures of Jupiter could fit three Earths next to each other—in the late 1800s. The Great Red Spot is getting smaller, and the reason is a mystery, Reuters reports. It was some 25,000 miles across in the late 19th century; by... More »

Hubble Captures Asteroid's Odd Death

They're the first such photographs ever

(Newser) - The Hubble Space Telescope continues to wow astronomers. NASA today released a series of photographs that the AP calls the "first pictures of a disintegrating asteroid." Hubble zoomed in for a closer look after other telescopes spotted something unusual in the asteroid belt between the orbits of Mars... More »

Hubble Spots Clouds on Faraway Planets

2 planets bear no resemblance to anything in our solar system

(Newser) - We see clouds pretty much every time we look up, but the Hubble Space Telescope spotted an exciting discovery for the science world—those white, puffy-looking things exist on planets outside of our own solar system. Two teams discovered thick layers of high-altitude clouds in the atmospheres of two exoplanets.... More »

Hubble Finds Water on 5 Distant Planets

Vapor detected in atmosphere, but none of the planets could support life

(Newser) - It's seen as more of a confirmation of theory than a startling discovery, but scientists have found water in the atmosphere of five huge planets outside our solar system. A potential sign of life? Not quite, explains the LA Times . These five gas giants (or "hot Jupiters")... More »

NASA 'Dumbfounded' by 6-Tailed Comet

(OK, technically it's a 'comet-like' asteroid)

(Newser) - The Hubble telescope has spotted a spectacular, perplexing object in the middle of the Asteroid Belt: a rock with six "comet-like" dust tails streaming behind it. "We were literally dumbfounded when we saw it," David Jewitt, the head of the astronomy team studying the P/2013 P5, said... More »

Neil deGrasse Tyson Picks Holes in Gravity

For a start, he says, it should be called 'Angular Momentum'

(Newser) - Because it wouldn't be a sci-fi film if geeks didn't tear it to shreds on the Internet, celebrity astrophysicist Neil deGrasse Tyson has taken to Twitter to unravel what he deems the "mysteries of Gravity "—a film he says would more aptly be titled "... More »

New Telescope Will Be 10 Times Sharper Than Hubble

$700M Giant Magellan Telescope will be ready in 2022

(Newser) - Scientists are currently hard at work on a new telescope that promises to have 10 times the resolution of the Hubble Space Telescope—but we're going to have to wait awhile. So far, only one of an eventual seven massive mirrors has been completely cast and polished for the... More »

Hunch Leads Astronomer to New Neptune Moon

Planet's 14th moon is just 12 miles across

(Newser) - An astronomer poring over old images from the Hubble Space Telescope has discovered a previously unknown 14th moon of Neptune. SETI Institute researcher Mark Showalter—who has five other moon discoveries to his name—followed a hunch while studying ring segments around the planet and tracked a white dot to... More »

Astronomers Find Blue Planet

But you wouldn't want to live there

(Newser) - A space traveler might be forgiven for mistaking Earth for another planet known as HD189733b from a distance—they're both a pleasant shade of blue. As explains, astronomers have for the first time determined the color of a far-flung world, this one 63 light-years away. (They did... More »

Astronomers Spot Oldest Galaxy Yet

It's 13.3 billion years old, nearly as old as the universe

(Newser) - Our universe is a mind-boggling 13.7 billion years old, and now astronomers say they have found a galaxy that has been around since the universe was a spry 420 million years old, reports LiveScience . Called MACS0647-JD, the 13.3-billion-year-old galaxy is tiny, cosmically speaking, just 600 light years wide... More »

Hubble 'Travels' Back 13.2B Years

'Time-tunnel' composite bares space 'just' after Big Bang

(Newser) - An out-of-this-world composite photo of Hubble Space Telescope shots peers back to a time a "mere" 450 million years after the Big Bang. Dubbed the eXtreme Deep Field, or XDF, the photograph—made up of 2,000 snaps taken by the Hubble over 10 years—reveals nearly 5,500... More »

Oldest Spiral Galaxy Shocks Astronomers

'Grand-design' spiral formed only 3B years after Big Bang

(Newser) - An ancient galaxy has flabbergasted astronomers. The perfectly formed spiral galaxy was born eons ago, a mere 3 billion years after the Big Bang. But this galaxy type was considered impossible so early on, when the cosmos was too chaotic to mold a "grand-design" spiral. How did it appear?... More »

Moon No. 5 Found for Pluto

Just 6 miles across, P5 is Pluto's smallest moon yet

(Newser) - It's not a chapter in the Twilight series, but it is a new moon: astronomers have discovered a tiny fifth satellite revolving around distant Pluto, reports . One year after P4 was announced, now the Hubble Telescope has spied a fifth moon. Pluto's biggest moon, Charon, is... More »

Bye-Bye, Milky Way —in Just 4B Years

Andromeda galaxy will smash into it

(Newser) - Our Milky Way is on a crash course with the (relatively) nearby Andromeda galaxy, and the two are scheduled to smash into each other—in just 4 billion years, reports the Christian Science Monitor . Actually, the two galaxies will collide three times over the following 2 billion years, eventually forming... More »

New 'Water World' Confirmed

GJ 1214b water world may yield 'hot ice’ or ‘superfluid water'

(Newser) - A hot and steamy water world 40 light years away has been identified as the first known member of a whole new class of planets. Researchers using the Hubble space telescope have confirmed that planet GJ 1214b, first spotted in 2009 , contains a much higher proportion of water than any... More »
