Milky Way's Center Is a Black Hole 'Farm'

Researchers believe there are thousands

(Newser) - The center of our galaxy is teeming with black holes, sort of like a Times Square for strange super-gravity objects, astronomers have discovered. For decades, scientists theorized that circling in the center of galaxies, including ours, were lots of stellar black holes, collapsed giant stars where the gravity is so... More »

Galaxy With No Dark Matter Baffles Astronomers

NGC1052–DF2 is 'weird'

(Newser) - It's a double cosmic conundrum: Lots of stuff that was already invisible has gone missing. Astronomers have found a distant galaxy where there is no dark matter. Dark matter is called "dark" because it can't be seen. It is the mysterious and invisible skeleton of the universe... More »

Astronomers Detect Signal From 13.4B Years Ago

Signal shows dawn of the universe, possible evidence of dark matter

(Newser) - After the Big Bang, it was cold and black. And then there was light. Now, for the first time, astronomers have glimpsed that dawn of the universe 13.6 billion years ago when the earliest stars were turning on the light in the cosmic darkness, the AP reports. And if... More »

It's a Bird, It's a Plane, It's a ... Giant Disco Ball in the Sky?

Rocket Lab says its 'Humanity Star' will shine in the sky for next 9 months

(Newser) - What's being described as a "giant disco ball" was launched into space last week from a New Zealand sheep and cattle farm, and astronomers are miffed, the Guardian reports. Rocket Lab, the space exploration startup responsible for hurling the "Humanity Star" skyward, says the 3-foot-wide carbon-fiber orb... More »

No One Has Set Eyes on This in 150 Years. You Can

'Super blue blood moon' eclipse coming Jan. 31

(Newser) - Look up at the sky on Jan. 31 and you may witness a sight unseen for 150 years. For the first time since 1866, a total lunar eclipse will occur with the blue moon, or second full moon of the month, which—like the one visible on New Year's... More »

Earth Will Get a Spooky Visitor in 2018

Skull-shaped asteroid expected to zip by in November

(Newser) - Earth will get its own Halloween decoration next year, though a little late. In mid-November, a skull-shaped asteroid will make its second flyby past Earth since it was discovered just beyond the moon in October 2015. It went on to pass by Earth on Oct. 31, 2015, prompting it to... More »

Scientists to Check if This 'Messenger' Comes From Aliens

Green Bank telescope will scan 'Oumuamua for signs of alien technology

(Newser) - It's unlikely that the first object found to have visited our solar system from interstellar space is carrying a message from aliens, but scientists will listen for one anyway. Beginning Wednesday, the Green Bank telescope in West Virginia will observe the mysterious cigar-shaped 'Oumuamua across four radio transmission... More »

Meet 'Oumuamua, Our First Guest From Another Solar System

And scientists think there could be thousands more just like it passing through

(Newser) - Houston, we have a visitor—and astronomers think there could be 10,000 more just like it "lurking" in wait, as the Guardian puts it. Meet 1I/2017 U1, or 'Oumuamua (Hawaiian for "messenger" or "scout"), which scientists say is an asteroid from another solar system—... More »

'We Are Dealing With Our 1st Truly Identified Alien Visitor'

Astronomers believe they've confirmed object arrived in our solar system from another

(Newser) - There's something strange in the solar neighborhood. "We've never seen anything like this before," Rob Weryk tells the New York Times . Earlier this month, the astronomer at the University of Hawaii Institute for Astronomy discovered a mysterious object zipping through our solar system. Calculations show it... More »

It Seems Likely Solar System Is Hiding Huge Planet

NASA unveils new evidence for mysterious 'Planet Nine'

(Newser) - Astronomically inclined conspiracy theorists have long been predicting the Earth's demise in a collision with a rogue planet called "Niburu" or "Planet X" biding its time out of sight somewhere in the solar system, CNET reports. In fact, Niburu was "supposed" to crash into Earth just... More »

This Saturday May Be the End of the World, 'Researcher' Says

A mix of astronomy and biblical prophecy

(Newser) - If you had big plans this weekend, David Meade regrets to inform you that the world will be ending Saturday. Meade, a Christian numerologist and self-described "researcher," says Sept. 23 is foretold in the Bible's Book of Revelation as the day a series of catastrophic events will... More »

Repeating Signal From Deep Space Heard Again

FRB 121102 likely a natural occurrence

(Newser) - Astronomers have detected a rare radio signal that originated about 3 billion years ago in a galaxy far, far away. And as one expert puts it, the source is "kind of perplexing." Fast radio bursts, millisecond-long pulses of radio emission from beyond our galaxy, were first discovered a... More »

What to Expect From This Weekend's Perseid Meteor Shower

NASA debunks a rumor

(Newser) - Last year's Perseid meteor shower was an extravaganza . Don't expect the same this year. While astronomers are expecting a decent 150 meteors per hour during peak hours between midnight and dawn on Aug. 12 and 13—a little less than the 200 per hour visible in 2016—NASA'... More »

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 »

Observatory Gives Real-Time View of Doomed Comet

The newly discovered comet is headed straight for the sun

(Newser) - Scientists at the US Naval Research Laboratory discovered a brand-new comet Thursday morning—just in time for it to smash into the sun, CNET reports. It's unclear if the comet will survive long enough to even get a name. The "sungrazing comet"—a poetic name for a... More »

The Moon Is Older Than We Previously Thought

It's 4.51B years old, according to a new study

(Newser) - It turns out the moon is older than many scientists suspected: a ripe 4.51 billion years old. That's the newest estimate, thanks to rocks and soil collected by the Apollo 14 moonwalkers in 1971, the AP reports. A research team reported Wednesday that the moon formed within 60... More »
