Possible New ‘Mini-Moon’ Detected in Orbit Around Earth

Astronomers from the Catalina Sky Survey say they have detected a rare mini-moon around Earth. Sadly, we shouldn’t get too attached to our new natural satellite, as the rock—if that’s indeed what it is—will only hang around for a few months.Read more...

Nasa's InSight lander records hundreds of marsquakes on red planet

InSight, which touched down in 2018, proves beyond doubt that Mars is seismically activeThe latest robot to land on Mars has felt the ground shake beneath its feet, whirlwinds tear across the surface and sudden blasts of air shoot past like “atmospheric tsunamis”.The measurements are the first to be released from Nasa’s InSight lander, which touched down in the barren expanse of Elysium Planitia in November 2018 on a mission to investigate the planet’s interior.

How to deflect an asteroid

On April 13, 2029, an icy chunk of space rock, wider than the Eiffel Tower is tall, will streak by Earth at 30 kilometers per second, grazing the planet's sphere of geostationary satellites. It will be the closest approach by one of the largest asteroids crossing Earth's orbit in the next decade.Observations of the asteroid, known as 99942 Apophis, for the Egyptian god of chaos, once suggested that its 2029 flyby would take it through a gravitational keyhole — a location in Earth's gravity field...

Getting to know 2015 TG 387, aka "the Goblin," an unconfirmed dwarf planet lurking in the Ort cloud

Have you heard of the Goblin? It's a likely dwarf-sized planet named that because it was discovered around Halloween, 2015. The Goblin travels in a 32-thousand-year orbit around our sun. It is currently 7.5 billion miles away, somewhere in the mysterious Oort Cloud area of the solar system. The Goblin is one of the farthest known objects within our solar system. Image: YouTube

German Man Finds Rock From Early Solar System in His Front Yard

Scientists have released their initial analysis of a meteorite that fell over Europe last September. They report that the rock, the remnant of a daytime bolide that impacted Earth with an energy of 0.48 kilotons of TNT (around this much), is a carbonaceous chondrite—the kind of meteor that contains material from the…Read more...

Oh Yeah, Betelgeuse Is Definitely Looking Weirder

At this point, we’re all crossing our fingers that the dying star Betelgeuse will hurry up and explode already, because who doesn’t love a good show? The red giant star (visible in the constellation Orion) has been growing dimmer since late last year, leading many to speculate it could soon go supernova. Scientists…Read more...

Mysterious Object Beyond Pluto Could Help Explain How Our Solar System Formed

Nothing you encounter is truly “pristine.” Nearly every atom on our planet has been processed in some way, either by humans, the Sun, Earth’s core, or other influences. But on New Year’s Day 2019, the New Horizons mission flew past one of the most pristine objects in the solar system: Arrokoth, an object far beyond…Read more...

Are physics and astronomy about to experience a cultural shift?

A new report calls for doubling the number of undergrad degrees awarded to black students in physics and astronomy by 2030. In the United States, black students earned a total of 223 bachelor's degrees in physics and just 10 in astronomy in 2018.The report found that unsupportive environments in physics and astronomy departments and systemic financial challenges faced by black students contributed to the underrepresentation of black students. Black students have been systematically excluded fro...

Solar Orbiter to capture first images of Sun's north, south poles

Solar Orbiter is a joint project between NASA and the European Space Agency.The mission aims to study the heliosphere, and to uncover information about the Sun's internal structure, magnetic field, and activity cycle.Solar Orbiter is set to ascend the ecliptic plane by the end of 2021, when it will begin imaging the Sun. The Solar Orbiter is set to launch Monday on its mission to study the Sun and photograph its north and south poles for the first time.The mission is a joint project between N...

Comet 67P Repeatedly Changed Color During the Historic Rosetta Mission

A review of data taken over the course of the two-year Rosetta mission shows that comet 67P/Churyumov-Gerasimenko was sometimes reddish in appearance, while at other times it assumed a bluish hue. Sounds weird, but scientists have come up with a sensible explanation that doesn’t involve aliens with paint guns. Read more...

"August Strindberg once claimed in his profound, deranged seriousness that the stars in the sky were peepholes in a wall."

I'm reading that in "My Struggle: Book 1" by Karl Ove Knausgaard (p. 205). Knausgaard goes on to other things, but I want the original Strindberg. I find this on the internet...But that's from a play — "The Butcher's Apron" — by Charles Tidler in which Strindberg is a character.I can't find the original Strindberg. When I read the sentence in the Knausgaard book, I imagined the stars as peepholes for those watching us from the other side of the sky.But in that Tidler play, it's the other way aro...

Breathtaking image of a red giant star swallowing another star

Astronomers captured this incredible image of a double-star system where a red giant star appears to have "engulfed the other (star) which, in turn, spiraled towards its partner provoking it into shedding its outer layers." The scientists spotted this astounding event using the Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope in the Chilean Andes. From the European Southern Observatory's (ESO) announcement: Thanks to new observations with ALMA, complemented by data fr...

Where are the Voyager spacecraft headed and what might they encounter next?

In this video on the UK-based V101 Science YouTube channel they ask the musical question: "What will Voyager 1 and 2 encounter next?" Next stop for Voyager 1? An obscure red dwarf known as Gliese 445 in the constellation Camelopardalis. It will take the then long-dead spacecraft over 38,000 years to get there. Voyager 2 is hellbound in the direction of Sagittarius and will arrive in the neighborhood in some 40,000 years. Its first encounter will be with Ross 248 in the constellation of Andromed...

The five: large telescopes

As the most detailed images of the sun are released this week, we look at other huge telescopes and their discoveriesThis week astronomers released the highest resolution of images taken of the sun’s stormy surface. The Daniel K Inouye Solar Telescope in Hawaii is the largest solar telescope in the world. The images reveal the nugget-like structures that make up the solar surface, each the size of France. The image is the start of a 50-year study of our closest star by the scientists working at ...

NASA finds real uses for VR and AR in astronomy and engineering

Years after the advent of decent VR hardware, there are still precious few ways the technology has been employed as anything other than a game or gimmick. One team at NASA, however, has been assembling useful science and engineering applications, with promising and unique results. Studying the astronomical number of stars in our galaxy is generally done using legacy tools, scattered databases, perhaps even paper and pencil. And as such it can be hard to use that great multi-purpose pattern re...

An Earth-sized planet found in the habitable zone of a nearby star

A few months ago a group of NASA exoplanet astronomers, who are in the business of discovering planets around other stars, called me into a secret meeting to tell me about a planet that had captured their interest. Because my expertise lies in modeling the climate of exoplanets, they asked me to figure out whether this new planet was habitable – a place where liquid water might exist. These NASA colleagues, Josh Schlieder and his students Emily Gilbert, Tom Barclay and Elisa Quintana, had been s...
