The night sky offers us a variety of spectacles throughout the year, but for the remainder of the month, we have front-row seats to see—not one or two—but seven planets at once. Go to Source Launching no earlier than Wednesday, Feb. 26, NASA’s Lunar Trailblazer will help resolve an enduring mystery: Where is the moon’s water? After sharing a ride on a SpaceX Falcon 9 rocket with Intuitive Machines’ IM-2 launch—part of NASA’s CLPS (Commercial Lunar Payload Services) initiative—the small satellite will take several months to arrive in lunar orbit. […] A study published in Science Advances sheds new light on the mysterious origins of free-floating planetary-mass objects (PMOs)—celestial bodies with masses between stars and planets. Go to Source Mars, the next frontier in space exploration, still poses many questions for scientists. The planet was once more hospitable, characterized by a warm and wet climate with liquid oceans. But today Mars is cold and dry, with most water now located below the surface. Understanding how much water is stored offers critical information for energy […] Intuitive Machines made history last year as the first private company to put a robot on the moon, although the triumph was marred by the lander tipping onto its side. Go to Source Geochemical evidence from laboratory experiments for a potential solid inner core at the center of Mars is reported in Nature Communications. Go to Source Chinese astronomers have analyzed the data from NASA’s Swift observatory, which extensively observed an outburst of the cataclysmic variable system known as GK Persei. Results of the study, published February 20 on the arXiv preprint server, shed more light on the nature of this system. Go to Source In 2007, astronomers discovered the Cosmic Horseshoe, a gravitationally lensed system of galaxies about 5.5 billion light-years away. The foreground galaxy’s mass magnifies and distorts the image of a distant background galaxy whose light has traveled for billions of years before reaching us. The foreground and background galaxies are in such perfect alignment that they […] Seven planets grace the sky at the end of February in what’s known as a planetary parade, though some will be difficult to spot with the naked eye. Go to Source High above Earth’s poles, intense electrical currents called electrojets flow through the upper atmosphere when auroras glow in the sky. These auroral electrojets push about a million amps of electrical charge around the poles every second. They can create some of the largest magnetic disturbances on the ground, and rapid changes in the currents can […] NASA’s Lucy spacecraft has its next flyby target, the small main belt asteroid Donaldjohanson, in its sights. By blinking between images captured by Lucy on Feb. 20 and 22, this animation shows the perceived motion of Donaldjohanson relative to the background stars as the spacecraft rapidly approaches the asteroid. Go to Source […] In the 1970s, images from the NASA Mariner 9 orbiter revealed water-sculpted surfaces on Mars. This settled the once-controversial question of whether water ever rippled over the red planet. Go to Source The chance that a football field-sized asteroid capable of destroying a city will strike Earth in 2032 has fallen to 0.001 percent, the European Space Agency said on Tuesday. Go to Source A research team from the Yunnan Observatories of the Chinese Academy of Sciences has recently published a study in The Astrophysical Journal that examines the inner and outer broad-line regions (BLRs) of active galactic nuclei (AGNs). Go to Source New observations of 2024 YR4 conducted with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) and facilities around the world have all but ruled out an impact of the asteroid with our planet. The asteroid has been closely monitored in the past couple of months as its odds of impacting Earth in 2032 rose […] |
