Spin flips show how galaxies grow from the cosmic web

The large-scale structure of the universe is traced by the distribution of galaxies. This 'cosmic web' consists of giant filamentary structures linking massive clusters of galaxies.
The new study finds that galaxies with bigger bulges tend to spin perpendicular to the filaments in which they are embedded, while galaxies with smaller bulges tend to spin parallel to these filaments.
"I Astronomers find a "cataclysmic" pair of stars with the shortest orbit yet
Sunday, 09 October 2022 10:15 Write a comment
Nearly half the stars in our galaxy are solitary like the sun. The other half comprises stars that circle other stars, in pairs and multiples, with orbits so tight that some stellar systems could fit between Earth and the moon.
Astronomers at MIT and elsewhere have now discovered a stellar binary, or pair of stars, with an extremely short orbit, appearing to circle each other every 51 minu Overlapping galaxies VV 191 in Webb and Hubble composite image

By combining data from the NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space Telescope, researchers were able to trace light that was emitted by the large white elliptical galaxy on the left through the spiral galaxy on the right and identify the effects of interstellar dust in the spiral galaxy. This image of galaxy pair VV 191 includes near-infrared light from Webb, and ult A day at the beach for life on other worlds

New simulations show that truly Earth-like exoplanets with oceans and continents, and beaches along the boundaries, may be much more common around red dwarfs than previously expected. This means ongoing and future exoplanet survey missions can expect to find multiple Earth-analogs for further study before the end of the decade.
The "habitable zone" is defined as the range of orbits around JPL developing more tools to help search for life in deep space

A team at the Lab has invented new technologies that could be used by future missions to analyze liquid samples from watery worlds and look for signs of alien life. Are we alone in the universe? An answer to that age-old question has seemed tantalizingly within reach since the discovery of ice-encrusted moons in our solar system with potentially habitable subsurface oceans.
But looking for NASA's Juno gets highest-resolution close-up of Jupiter's moon Europa
Sunday, 09 October 2022 10:15 Write a comment
Observations from the spacecraft's pass of the moon provided the first close-up in over two decades of this ocean world, resulting in remarkable imagery and unique science.
The highest-resolution photo NASA's Juno mission has ever taken of a specific portion of Jupiter's moon Europa reveals a detailed view of a puzzling region of the moon's heavily fractured icy crust.

Sunday, 09 October 2022 10:15 Write a comment
When the Chelyabinsk fireball exploded across Russian skies in 2013, it littered Earth with a relatively uncommon type of meteorite. What makes the Chelyabinsk meteorites and others like them special is their dark veins, created by a process called shock darkening. Yet, planetary scientists have been unable to pinpoint a nearby asteroid source of these kinds of meteorites - until now.

SpaceX aborts launch of two communication satellites into orbit
Saturday, 08 October 2022 11:17 Write a comment
The launch of two SpaceX communications satellites from Cape Canaveral Space Force Station on Friday was aborted again and is now scheduled for Saturday.
The Galaxy 33 and 34 satellites had been scheduled to lift off at 7:06 p.m. and to help the telecommunications company Intelsat maintain service in North America. However, the launch was bumped back a day to Saturday night.

NASA had been designing lunar bases for decades before Armstrong first set foot on the moon

It's only natural to look at the moon and wonder what it would be like to live there. Thanks to Buzz Aldrin who landed there in 1969, we know it's a magnificent desolation. Even before the Apollo missions science fiction writers and scientists knew how desolate the place was. But, as far back as the late 19th century, they also saw it as a natural outpost. So did NASA, the former Soviet Union, and their respective militaries. And, that led to people on both sides drawing up elaborate plans for moon bases.
