‘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…

Hubble Studies a Potential Galactic Merger

NeRD

3 min read Hubble Studies a Potential Galactic Merger This NASA/ESA Hubble Space Telescope image captures the dwarf irregular galaxy NGC 5238. ESA/Hubble & NASA, F. Annibali This NASA/ESA Hubble Space Telescope image features the dwarf irregular galaxy NGC 5238, located 14.5 million light-years from Earth in the constellation Canes Venatici. Its unexciting, blob-like appearance seems to resemble an oversized star cluster more than a classic image of a galaxy. Its lackluster appearance belies its complicated structure, which is the subject of a great deal of research. As the image…

Sun blasts out 2nd X-class flare this week, triggers more radio blackouts (video)

NeRD

The sun continues firing off solar flares during what has been a period of intense activity.  Sunspot AR3738 might be making its exit as it rotates out of our view on the sun’s western limb, but not before firing off a powerful X-class solar flare, the strongest of its kind. The solar flare from sunspot AR3738 occurred Tuesday morning (July 16) at 9:26 a.m. EDT (1326 GMT). A shortwave radio blackout in conjunction with the latest event was reported over mostly the Atlantic Ocean and also noted across much of Africa, Europe, and…

NASA’s Webb Investigates Eternal Sunrises, Sunsets on Distant World

NeRD

6 Min Read NASA’s Webb Investigates Eternal Sunrises, Sunsets on Distant World Artists concept of WASP-39 b (full image below). Near-infrared spectral analysis of terminator confirms differences in morning and evening atmosphere Researchers using NASA’s James Webb Space Telescope have finally confirmed what models have previously predicted: An exoplanet has differences between its eternal morning and eternal evening atmosphere. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but similar mass to Saturn that orbits a star about 700 light-years away from Earth, is tidally locked…

Scientists call the region of space influenced by the sun the heliosphere – but without an interstellar probe, they don’t know much about its shape

NeRD

This article was originally published at The Conversation. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights. Sarah Spitzer is a research fellow in Climate and Space Sciences and Engineering at the University of Michigan. The sun warms the Earth, making it habitable for people and animals. But that’s not all it does, and it affects a much larger area of space. The heliosphere, the area of space influenced by the sun, is over a hundred times larger than the distance from the sun to the Earth. The sun is a…

Is Earth’s weather getting weirder?

NeRD

Severe turbulence, record rainfall, killer heatwaves and raging wildfires to name but a few: is it just me, or is “Is Earth’s weather getting weirder?” The answer? Yes. Well, sort of.  These weather events have happened in the past, but the problem is nowadays they’re happening more frequently and to a far greater extent.  What’s causing this uptick in “global weirding” and is there anything we can do about it? Space.com spoke with a leading climate scientist Katharine Hayhoe to learn more about this strange surge in weird weather events…

Hubble Measures the Distance to a Supernova

NeRD

3 min read Hubble Measures the Distance to a Supernova This NASA/ESA Hubble Space Telescope image features the galaxy NGC 3810. ESA/Hubble & NASA, D. Sand, R. J. Foley Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it’s a difficult one to complete. We can only measure the distances to a few nearby objects like the Sun, planets, and some nearby stars directly. Beyond that, astronomers need to use…

Cosmic crime scene reveals ancient supernova aftermath of dead star merger

NeRD

The ultimate cosmic “cold case” has lingered for 843 years — and now, space detectives may have solved it at last. In 1181 AD, as the Genpei War raged in Japan, a mystery “guest star” briefly flashed over Asia’s skies. Astronomers had puzzled over the brief event until 2021, when a team of researchers tracked it to its location in the cosmos. Yet, the cause of the event, now designated supernova (SN) 1181, remained shrouded in mystery. That was until a team of scientists used computer modeling and observational analysis…
