Runaway ‘failed star’ races through the cosmos at 1.2 million mph

NeRD

A newly discovered rogue stellar body may well be a “failed star,” but it certainly isn’t a failure when it comes to velocity!  The potential brown dwarf is racing through our Milky Way galaxy at 1.2 million mph (1.9 million kph). That’s about 1,500 times faster than the speed of sound! Thankfully, this cosmic runaway is heading toward the center of the Milky Way and not toward us. However, the object is traveling so fast that it could eventually escape our galaxy entirely.  The incredible speed of this newly uncovered…

Jupiter’s surreal clouds swirl in new van Gogh-esque view from NASA’s Juno probe (photo)

NeRD

Vivid clouds swirl across Jupiter’s skies like colorful brushstrokes across a painting in a new photo from NASA‘s Juno spacecraft.  The image, taken during the spacecraft’s 61st close flyby of Jupiter on May 12, 2024, hones in on activity in the planet’s northern hemisphere. Juno was approximately 18,000 miles (29,000 kilometers) above Jupiter’s cloud tops when it captured this new view, highlighting the planet’s persistent storms and colorful bands created by strong winds in its atmosphere.  “It provides a detailed view of chaotic clouds and cyclonic storms in an area…

Chinese astronauts simulate a debris-strike emergency on the Tiangong space station (video)

NeRD

China’s Shenzhou 18 mission staged an emergency drill recently to boost preparedness aboard the country’s space station. Shenzhou 18 commander Ye Guangfu and crewmates Li Cong and Li Guangsu conducted the drill in mid-July to practice procedures for the case of a decompression event aboard the Tiangong space station. The crew worked in collaboration with the ground team in Beijing, simulating the whole process of emergency response to a simulated scenario of space debris striking Tiangong and causing decompression. The astronauts of China’s Shenzhou 18 mission simulate a debris-strike emergency…

Mercury has a layer of diamond 10 miles thick, NASA spacecraft finds

NeRD

The solar system’s tiniest planet may be hiding a big secret. Using data from NASA‘s MESSENGER spacecraft, scientists have determined that a 10-mile-thick diamond mantle may lie beneath the crust of Mercury, the closest planet to the sun.  Mercury has long puzzled scientists as it possesses many qualities that aren’t common to other solar system planets. These include its very dark surface, remarkably dense core, and the premature end of Mercury’s volcanic era.  Also among these puzzles are patches of graphite, a type (or “allotrope”) of carbon on the surface…

SpaceX wins $113 million contract to launch advanced NOAA climate satellite

NeRD

SpaceX just added another mission to its already crowded launch manifest. Elon Musk‘s company won the launch contract for the U.S. National Oceanic and Atmospheric Administration’s (NOAA) JPSS-4 satellite. If all goes according to plan, JPSS-4 will lift off atop a Falcon 9 rocket from California’s Vandenberg Space Force Base in 2027. The firm, fixed-price contract is worth $112.7 million, “which includes launch services and other mission-related costs,” NASA officials wrote in an update on Monday (July 22).  The JPSS (“Joint Polar Satellite System”) program is a cooperative effort of…

Alien weather report: James Webb Space Telescope detects hot, sandy wind on 2 brown dwarfs

NeRD

The James Webb Space Telescope (JWST) has discovered stormy weather in the sky of two brown dwarfs in the most detailed weather report yet from such “failed stars.” The two brown dwarfs form a binary pair called WISE 1049AB that was discovered by NASA‘s Wide-field Infrared Survey Explorer (WISE) in 2013; the duo sits just 6.5 light-years away from us. They are the closest brown dwarfs to our sun, and thus make an excellent target for the James Webb Space Telescope‘s powerful infrared instruments. A brown dwarf is an object…

Europe on the moon: ESA targeting 2031 for 1st ‘Argonaut’ lunar lander mission

NeRD

A European moon lander being developed to provide the continent autonomous access to the moon is targeted to launch in 2031, according to a development call published last week by the European Space Agency (ESA).  The robotic lander, called Argonaut, is expected to lift off on an Ariane 6 rocket, which after a long series of delays made its debut flight on July 9.  ESA wants Argonaut to perform multiple deliveries of cargo and science instruments to the moon. The lander will be capable of ferrying up to 4,600 pounds…

‘A dark day for lunar science:’ Scientists shocked as NASA cancels VIPER moon rover

NeRD

It is a classic wait-a-minute Moon moment. The message from NASA last week: “NASA Ends VIPER Project, Continues Moon Exploration.” The space agency’s Volatiles Investigating Polar Exploration Rover (VIPER) project had undergone a comprehensive internal review. NASA found price tag sticker shock, delays to the launch date, and risk of future cost growth – reasons to “stand down” the lunar ice-hound mission.  Some disassembly required At this point in time, NASA had put in $450 million into VIPER. NASA said it’s planning to disassemble and reuse VIPER’s instruments and components…
