Why an Animated Flying Cat With a Pop-Tart Body Sold for Almost $600,000

In the 10 years since Chris Torres created Nyan Cat, an animated flying cat with a Pop-Tart body leaving a rainbow trail, the meme has been viewed and shared across the web hundreds of millions of times. On Thursday, he put a one-of-a-kind version of it up for sale on Foundation, a website for buying and selling digital goods. In the…

Evidence for white dwarfs consuming Earth-like worlds

For the first time, astronomers have detected the vaporized remains of the crusts of long-dead Earth-like and Mars-like planets in the atmospheres of white dwarf stars. Source: https://earthsky.org/space/vaporized-earth-like-mars-like-crusts-white-dwarf-stars…

Water worlds may be abundant in our galaxy

A new study suggests that our Milky Way galaxy is filled with planets like Earth, containing continents and oceans. If so, life might be common in the Mlilky Way. Source: https://earthsky.org/space/water-common-on-planets-pebble-accretion-milky-way…

Why does this galaxy look older than its years?

To the extent that we can see them, galaxies in the very early universe should look relatively young and unformed. But galaxy ALESS 073.1 is a surprise to astronomers: it looks more mature than we’d have any reason to expect. Why? Source: https://earthsky.org/space/galaxy-looks-older-than-its-years-aless-073-1…

Image: Hubble views a baby star’s tantrums

Herbig-Haro objects are some of the rarer sights in the night sky, taking the form of thin spindly jets of matter floating among the surrounding gas and stars. The two Herbig-Haro objects cataloged as HH46 and HH47, seen in this image taken with the NASA/ESA Hubble Space Telescope, were spotted in the constellation of Vela (the Sails), at a distance of…

Can air pollution help us find alien life?

To find alien life in our universe, scientists have considered searches for optical lasers or even giant energy-harvesting structures known as Dyson spheres. Now they’re suggesting a more mundane sort of search, a hunt for air pollution in exoplanet atmospheres. Source: https://earthsky.org/space/can-pollution-help-us-find-alien-life…

A unique prototype of microbial life designed on actual Martian material

Experimental microbially assisted chemolithotrophy provides an opportunity to trace the putative bioalteration processes of the Martian crust. A study on the Noachian Martian breccia Northwest Africa (NWA) 7034, composed of ancient (ca. 4.5 Gyr old) crustal materials from Mars has delivered a unique prototype of microbial life experimentally designed on actual Martian material. As the researchers show in the current issue…
