A mysterious 'Rosetta Stone' explosion reveals a missing link behind solar eruptions

The failed portion of a solar eruption on March 13, 2016. NASA/Solar Dynamics Observatory Scientists recently examined a solar eruption from 2016 that seemed to defy categorization. They named it the "Rosetta Stone" since it connected three different types of eruptions. Their research now suggests that all three forms of solar eruptions may have the same origin.

Solar Eclipse Visible In Sacramento Area Early Thursday Morning

(CBS13/CNN) — The moon will partially block out the sun this Thursday to create a “ring of fire” solar eclipse. Some people in the Northern Hemisphere will be able to catch the first of two solar eclipses this year on June 10. A solar eclipse happens when the moon crosses between the sun and the Earth, which blocks a portion of the sun’s rays, according to NASA. This eclipse is an annular eclipse, meaning the moon is far enough away from the Earth that it appears smaller than the sun. When the m...

Organic molecules reveal clues about dying stars and outskirts of Milky Way

Researchers from the University of Arizona have detected organic molecules in planetary nebulae, the aftermaths of dying stars, and in the far reaches of the Milky Way, which have been deemed too cold and too removed from the galactic center to support such chemistries. They present their findings at the 238th Meeting of the American Astronomical Society, or AAS, held virtually from June 7-9.

Diversity, equity and inclusion nonsense: Walter Williams

Check out any professional and most college basketball teams. Their starting five, and most of their other 10 players, are Black, as is 80 percent of the NBA. This does not come anywhere close to the diversity and inclusion sought by the nation’s social justice warriors. Both professional and college coaches have ignored and threw any pretense of seeking diversity and inclusiveness. My question to you is: Would a basketball team be improved if coaches were required to include ethnically diverse ...

Betelgeuse likely won't die as a supernova in your life. But astronomers are finding 'red nova' stars that may soon violently explode.

The red super-giant star Betelgeuse has dramatically dimmed, leading to speculation of an imminent supernova. But that may not happen for 1 million years. A more common but less widely known way for stars to die is a red nova: When a bigger star rips a smaller one to shreds and gobbles it up. Astronomer Larry Molnar and his colleagues have worked to define the stages that lead to a red nova and identified seven candidates in a near-final stage. Ongoing surveys of the night sky may soon turn up...

Simply Begin Again

Public Service Announcement: According to the Farmer’s Almanac, the American Astronomical Society, and the US Naval Observatory, today is not the beginning of a new decade. Rather, that would be 1/1/21. If you write software, you’ll recognize that it’s a classic fencepost error. If you are a philosophy major like Amy, you’ll tell me that a decade is “any ten year period of time, starting whenever you want it to.” Regardless, happy Julien New Year.

Astronomers find signatures of a 'messy' star that made its companion go supernova

On Jan. 10 at the 2019 American Astronomical Society meeting in Seattle, an international team of astronomers announced that they have identified the type of companion star that made its partner in a binary system, a carbon-oxygen white dwarf star, explode. Through repeated observations of SN 2015cp, a supernova 545 million light years away, the team detected hydrogen-rich debris that the companion star had shed prior to the explosion.

'Light Echoes' of Black Hole Reveal Clues Behind Dazzling X-Ray Flares

An instrument aboard the International Space Station has helped reveal how black holes release brilliant flares of X-rays, a new study finds. Previous research found that when gas and dust get sucked into black holes, they explode with bursts of high-energy X-rays that usually last about a year. A better understanding of these outbursts, dubbed transient events, might shed light on how black holes influence the fates of their host galaxies. However, scientists have debated where these bright f...

Hubble team has bad news for aliens: Red dwarfs seem to wipe out life’s necessities

Red dwarf stars have been seen as the biggest potential frontier for alien life, in part because they’re the most common stars in our galaxy. But observations made using the Hubble Space Telescope suggest that the frontier might turn out to be a desert. “We may have found the limit to habitable planets,” said Carol Grady, a co-investigator on the Hubble observations from Eureka Scientific in Oakland, Calif. She laid out the research team’s findings today at the American Astronomical Society’s wi...
