The aurora overload is expected to continue and possibly get even more impressive as a coronal mass ejection (CME), a burst of plasma from the sun's upper atmosphere that erupted from the sun Feb. Similar red aurora sightings have been reported by photographers in Scotland and Norway. Quebec, Canada-based aurora hunter Mike MacLellan shared with his catches: out of this world photographs of the horizon ablaze with bright neon-like green that turns into orange, red and purple higher up in the sky. The latest wave of dancing polar lights has been especially striking, as it arrived in rare shades of red that require higher concentrations of solar wind particles to penetrate deeper into Earth's atmosphere. Twitter has been virtually awash over the past days with skywatchers' images and accounts of spectacular aurora sightings. And space weather forecasters promise that more is on its way.

The 6U cubesat, built by the Japanese Aerospace Exploration Agency (JAXA) and the University of Tokyo, imaged the comet for six hours on Feb. "EQUULEUS successfully photographed Comet ZTF (Comet C/2022 E3) from space!" the EQUULEUS team said in a tweet accompanying the image sequence shared on Tuesday (Feb. The comet - also called the green comet for its hue or the Neanderthal comet, as it hasn't visited Earth since the era of the Neanderthals - can be seen in the video sequence shared on Twitter as a fuzzy white dot traversing a star-studded black-and-white background.
Tuesday, February 21, 2023: Japan's cubesat EQUULEUS, which hitched a ride to the moon aboard NASA's Artemis 1 mission in November last year, took a video of Comet C/2022 E3 (ZTF) earlier this month, about two weeks after the ice ball's closest approach to Earth. – Tereza Pultarova Cubesat that launched to the moon on Artemis 1 sees green comet M92 is one of the oldest globular clusters in the Milky Way, consisting of stars that formed 12 to 13 billion years ago, when the universe was only a few hundreds of thousands of years old. If an inhabited planet like Earth were to orbit one of those stars, the creatures on its surface would have a magnificent view of the night sky, which would shine with thousands of stars that would be thousands of times brighter than those humans can see from Earth. The whole cluster, about 100 light-years wide, has 300,000 stars squeezed inside of it. The image, captured by Webb's Near Infrared Camera (NIRCam), reveals only a small portion of the M92 cluster. "Below this boundary are brown dwarfs, which are so low-mass that they're not able to ignite hydrogen in their cores." "This is very close to the boundary where stars stop being stars," Cohen said. Some of the stars in this image are tiny, only 0.1 the mass of our sun, Roger Cohen, an astronomer at Rutgers University and one of the scientists behind the observations, said in the statement. Primarily built to study the most distant objects in the far-away reaches of the universe, Webb easily detected the multitude of stars inhabiting the cluster, including the dim and cool ones that were invisible to its predecessor, the Hubble Space Telescope. It took only one hour to capture the sparkling image above, according to a statement (opens in new tab) by the Space Telescope Science Institute, which operates the observatory. The James Webb Space Telescope, or Webb, observed the globular cluster, also known under the shortcut M92, early after coming online. Wednesday, February 22, 2023: The James Webb Space Telescope has looked inside one of the oldest components of our Milky Way galaxy, the Messier 92 globular cluster located some 27,000 light-years away from Earth.
