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...

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...

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...

There is no dark matter. Instead, information has mass, physicist says

Researchers have been trying for over 60 years to detect dark matter. There are many theories about it, but none are supported by evidence. The mass-energy-information equivalence principle combines several theories to offer an alternative to dark matter. None The  “discovery” of dark matter We can tell how much matter is in the universe by the motions of the stars. In the1920s, physicists attempting to do so discovered a discrepancy and concluded that there must be more matter in the univ...

First asteroid found inside orbit of Venus: Caltech

Some extra-planetary Caltech news to take your mind off Earth Reports Caltech: “A rare asteroid orbiting snugly within the inner confines of our solar system has been discovered by Caltech's Zwicky Transient Facility, or ZTF, a survey camera based at Palomar Observatory. The newfound body, named 2020 AV2, is the first asteroid found to orbit entirely within the orbit of Venus.” 2020 AV2 orbits entirely within the orbit of Venus.PHOTO: Bryce Bolin/Caltech More from the Caltech media announc...

Stardust older than the Earth and sun found in Australian meteorite

Granules, shed by dying stars over 5bn years ago, are oldest known solid material on EarthStardust that formed more than 5bn years ago, long before the birth of the Earth and the sun, has been discovered in a meteorite that crashed down in Australia, making it the oldest known solid material on the planet.The tiny granules of stardust, shed by ancient stars as they expired, reveal clues about how stars formed in the Milky Way. The meteorite accumulated the stardust during the billions of years i...
