Friday, December 13The bright gibbous Moon passes 4° north of Uranus at 5 A.M. EST. At that time, the Moon sits in Aries the Ram, while Uranus is just over the border in far western Taurus the Bull. The two set together around 5 A.M. local time. You might have better luck spotting the ice … Read more
NASA’s Ingenuity Mars helicopter rests on the sandy dunes of the Red Planet’s surface following a crash during its final flight in January.

But what happens when a crash occurs hundreds of millions of miles … Read more
Scientists have discovered seven more “dark comets,” and analysis of this haul suggests that the puzzling planetoids are divided into two distinct families, further deepening the mystery of why these objects look like asteroids but behave like comets. Of late, the dividing line between asteroids and comets has become blurred. There are “main-belt comets,” also … Read more
Not long ago, the James Webb Space Telescope (JWST) peered into Cosmic Dawn, the cosmological period when the first galaxies formed less than one billion years after the Big Bang. In the process, it discovered something rather surprising. Not only were there more galaxies (and brighter ones, too!) than expected, but these galaxies had supermassive … Read more
A superflare erupts from a young sunlike star in this artist’s impression. Credit: CfA/Melissa Weiss Solar flares are bright flashes of light from the Sun that release large amounts of electromagnetic radiation. And while normal flares can release as much as 1025 joules of energy, so-called superflares, observed on other stars, are up to 10,000 … Read more
High-energy, powerful, and violent stellar explosions called “superflares” have been found to erupt from stars like the sun roughly once every 100 years, making these blasts far more common than scientists had thought. Solar flares, eruptions of high-energy radiation, can have serious effects on Earth, with the potential to impact communication systems and power infrastructure. … Read more

Ever wondered what happened to Bradward Boimler’s transporter duplicate? We already knew his death was faked by Section 31 and now we know the reason why: he’s leaping between multiverses as if he’s Doctor Strange, trying to stop whatever — or whoever — is tearing rifts between dimensions. And who else to accompany him on … Read more
NGC 1514 The Crystal Ball Nebula (NGC 1514) was discovered by German-born English astronomer William Herschel in 1790. Credit: Eric Coles/Bob Fera The constellation Taurus the Bull is an easy one to find in the Northern Hemisphere’s fall and winter skies. It stands opposite the Sun at the beginning of December. The head of the … Read more
Jupiter’s volcanic moon Io doesn’t appear to have a subsurface ocean of magma, resolving some issues about how Io’s volcanoes erupt and raising broader questions about similar magma oceans within other moons and planets. Data from previous missions had made planetary scientists wonder whether, rather than just pockets of melt, Io contained a 31-mile (50-kilometer) … Read more
