A broken cable smashed a hole 100 feet wide in the Arecibo Observatory, which searches for aliens and tracks dangerous asteroids

A cable broke and tore a hole in the Arecibo Observatory in Puerto Rico on Monday. The telescope had just reopened to study a potentially dangerous asteroid, shortly after Tropical Storm Isaias passed over the island. It's unclear why the cable broke, but the facility is closed again as engineers assess the damage. Visit Business Insider's homepage for more stories. One of the world's most prominent astronomical observatories has a hole. On Monday, a 3-inch-thick cable at the Arecibo Observat...

Arecibo Observatory returns from tropical storm Isaias lockdown to track asteroid for NASA

Arecibo's Planetary Radar Group quickly shift from storm response to track asteroid 2020 NK1. Before the Arecibo observations, 2020 NK1 was calculated to be one of the biggest threats out of all known asteroids on NASA's list of potential impactors, with about one chance in 70,000 of impacting the Earth between 2086 and 2101.

Talking to Aliens.

Daniel Oberhaus writes for Wired about the (so far hypothetical) problem of contacting aliens that begins by describing Sónar Calling GJ273b, “an interstellar messaging project by the nonprofit METI International that began in 2017” which “was notable for rehabilitating an extraterrestrial language developed by the physicists Yvan Dutil and Stephane Dumas in the late 1990s”: This custom symbolic system begins by introducing ET to numerals, and then progresses to more complex topics like human bi...

How colliding neutron stars could shed light on universal mysteries

Researchers have discovered an unusual pulsar - one of deep space's magnetized spinning neutron-star 'lighthouses' that emits highly focused radio waves from its magnetic poles. It is unusual because the masses of its two neutron stars are quite different -- with one far larger than the other.The breakthrough provides clues about unsolved mysteries in astrophysics -- including the expansion rate of the Universe (the Hubble constant).The discovery was made using the Arecibo radio telescope, Puert...

Giant Asteroid Will Fly By Earth On Wednesday, Close Enough To See By Telescope

(CNN) — An asteroid estimated to be 1.2 miles wide will fly by Earth early Wednesday morning, but it’s not expected to collide with our planet. The asteroid is called 52768 (1998 OR2), and it was first spotted in 1998. On April 29, it will pass within 3,908,791 miles of Earth, moving at 19,461 miles per hour. That’s still 16 times farther than the distance between Earth and the moon. The flyby is expected to occur at 5:56 a.m. ET, according to NASA’s Center for Near-Earth Object Studies. The cen...

Scientists Observe Potentially Hazardous Asteroid Buzz Past Earth With Its Own Moon (slashdot)

Meghan Bartels writes via Space.com: One of Earth's premier instruments for studying nearby asteroids is back to work after being rattled by earthquakes, and its first new observations show that a newly discovered space rock is actually two separate asteroids. The instrument is the planetary radar system at the Arecibo Observatory in Puerto Rico. The observatory was closed for most of January, after a series of earthquakes hit the island beginning on Dec. 28, 2019. The observatory reopened on Ja...

Little bits of previously unfinished data.

You may have noticed occasional bits of data from years past showing up in your queue. While running a completeness check I noticed some files that had never been completely analyzed. Some may have fallen through the cracks. Some may just be bad data that never made it through the splitters. I'm going to trickle them into the queue when the Arecibo queue is empty, just in case.

Astronomers detect mysterious repeated radio signal from faraway galaxy for second time

Fast radio bursts are short, millisecond-long radio waves that come from billions of light years outside of the Milky Way galaxy, and for the second time ever, scientists have detected one that has been repeated, suggesting that it's coming from the same location. The repeating fast radio burst (FRB) was one of 13 FRBs to be detected by the Canadian Hydrogen Intensity Mapping Experiment's (CHIME), a radio telescope in British Columbia’s Okanagan Valley, during its pre-commissioning run in the s...

Astronomers spot more mysterious radio signals from far outside the galaxy

Whenever some new “cosmic puzzle” crops up, you always have to be ready for the other shoe to drop. But just because something isn’t an alien message or Ringworld doesn’t mean it can’t be interesting science. Today’s shoe drop concerns “fast radio bursts” coming from a distant galaxy — but don’t expect a secret message from an advanced civilization. Fast radio bursts, or FRBs, are short, intense blasts of radio waves that come from far outside our galaxy. No one knows what causes them, but they’...

44 years after its first message to aliens, Arecibo Observatory calls for follow-up

The Arecibo Observatory today kicked off a student-focused competition to design a new message to beam to extraterrestrials, 44 years to the day since the first deliberate message was sent out from Arecibo’s 1,000-foot-wide radio telescope.. “Our society and our technology have changed a lot since 1974,” Francisco Cordova, the observatory’s director, said in a news release. “So if we were assembling our message today, what would it say? What would it look like? What one would need to learn to be...

Astronomers found a 'snowy' super-Earth less than 6 light-years away — and it may be the first planet we'll photograph beyond the solar system

Astronomers think they've found a "cold super-Earth" exoplanet orbiting Barnard's star. Barnard's star less than 6 light-years away from us and the closest single-star system to our sun. The new world is called Barnard's star b (or GJ 699 b) and is at least 3.2 times as massive as Earth. It orbits in the "snow line" of its parent star: a region at the edge of a star's habitable zone where scientists suspect most rocky planets form. This Earth-size exoplanet may be the first to be photographed ...

“We Survived”: A Year After Hurricane Maria, 25 Puerto Rican Women Tell Their Story

One year ago, Puerto Rico faced its most catastrophic storm in recent history. Hurricane Maria came barreling through on the early hours of September 20, knocking out the power and all communications methods almost instantly across the U.S. territory. And the massive storm, with its unforgivable rain and winds, was just the beginning.We all know the aftermath of the Category 4 hurricane was worse than anyone could have predicted: Puerto Ricans spent months without water or electricity, facing f...

A 'potentially hazardous' asteroid bigger than Earth's tallest skyscraper is about to fly near our planet

An asteroid called 2002 AJ129 will pass within about 2.6 million miles of Earth on February 4. The space rock may be 1,000 feet taller than the Burj Khalifa skyscraper. Astronomers are taking radar images of the "potentially hazardous" asteroid, though NASA says it has "zero" chance of hitting Earth within the next 100 years. Giant telescopes are being built to find similarly sized "city killer" asteroids that threaten our planet. Astronomers are keeping a close eye on a big space rock tha...

NASA captures glimpse of monster near-Earth asteroid 3200 Phaethon

Tiny space rocks fly past Earth all the time, but it's rare that a potential planet-killer makes an appearance in our neck of the woods. Earlier this month a massive asteroid named 3200 Phaethon passed by our planet at a totally safe distance of about 1.1 million miles. Researchers used the opportunity to get a better look at the potentially hazardous object and actually learned quite a bit about it. Using the Arecibo Observatory Planetary Radar in Puerto Rico, scientists were able to captur...

Pulsars V

A couple of years ago, astronomers announced the discovery of a pair of neutron stars in the widest orbit yet seen in such a system. The discovery wasn’t made by the pros, though. Instead, it was made by two high school students. The students found the binary by studying old observations of a pulsar — a neutron star that spins rapidly, emitting “pulses” of radio waves. Changes in the timing of the pulses revealed the companion star. Over the past decade, students from around the country have hel...
