Humans Will Fly Around The Moon In 2024, NASA Announces

Posted by in category: space travel

The mission to return humans to the Moon is moving on to its next phase, NASA has announced. While reporting the current analysis of the successful uncrewed Artemis I mission, the agency revealed when the first crewed mission will take place.

Artemis I was the first test flight for NASA’s megarocket Space Launch System (SLS) and Orion spacecraft and spent 25.5 days in space. Artemis II will be the first crewed flight to the Moon before Artemis III actually lands on the lunar surface.

What Plants Are Saying About Us

Posted by in categories: biotech/medical, food, habitats

Iwas never into house plants until I bought one on a whim—a prayer plant, it was called, a lush, leafy thing with painterly green spots and ribs of bright red veins. The night I brought it home I heard a rustling in my room. Had something scurried? A mouse? Three jumpy nights passed before I realized what was happening: The plant was moving. During the day, its leaves would splay flat, sunbathing, but at night they’d clamber over one another to stand at attention, their stems steadily rising as the leaves turned vertical, like hands in prayer.

“Who knew plants do stuff?” I marveled. Suddenly plants seemed more interesting. When the pandemic hit, I brought more of them home, just to add some life to the place, and then there were more, and more still, until the ratio of plants to household surfaces bordered on deranged. Bushwhacking through my apartment, I worried whether the plants were getting enough water, or too much water, or the right kind of light—or, in the case of a giant carnivorous pitcher plant hanging from the ceiling, whether I was leaving enough fish food in its traps. But what never occurred to me, not even once, was to wonder what the plants were thinking.

To understand how human minds work, he started with plants.

Galaxies’ missing matter may be found — but now there’s too much of it

Posted by in category: space

Most galaxies seemed to be missing a huge proportion of the matter we expected them to have – now researchers may have found its hiding spot, but the discovery contradicts accepted models of galaxy formation.

How Do Supermassive Black Holes Form? Study Reveals Huge Galaxy Mergers During Cosmic Noon Play an Important Role in This Celestial Formation

Posted by in categories: cosmology, evolution

The cosmos is full of mysteries, one of which is the existence of supermassive black holes. Though much effort has been granted to these celestial mysteries, the evolution and formation of such supermassive black holes are quite hard to explain.

Astronomers Just Discovered An Exotic Black Hole Deemed A ‘Needle In A Haystack’

Posted by in category: cosmology

Astronomers have found what they are calling a “cosmic needle in a haystack” in a galaxy next to our Milky Way. It is a dormant black hole that seems to have formed without the explosion of a dead star.

Researchers said on Monday that this black hole is different from all the others that we know of because it is “X-ray quiet.” This means that it doesn’t make a lot of X-ray radiation, which would indicate that it is eating nearby matter with its huge gravitational pull, and that it didn’t form in a supernova.

Black holes are very dense things with so much gravity that not even light can get out.
