Little Red Dots Lead To Big Discoveries
Names are a strange thing in astronomy. Sometimes scientists come up with grandiose, simple name, like the Extremely Large Telescope. Other times, they come up with unique sounding names, like quasars. And sometimes they come up with names that, while descriptive in some sense, are completely misleading in others. That is the case for Little Red Dots (LRD) - active galactic nuclei in the early universe that show up as a little red dot in the images captured by whatever telescope found them. However, they actually represent supermassive black holes hundreds of millions of times the size of our Sun. A new paper from Federica Loiacono and her colleagues at Istituto Nazionale di Astrofisica in Italy describes one of these behemoths they found with the James Webb Space Telescope at a period of the early universe, about 11 billion years ago, known as the “cosmic noon”.
UK is Considering a Mission to Venus to Search for Life
Is there life on Venus? The controversial detection of phosphine and ammonia hints that bacterial life could be surviving in the planet's milder upper atmosphere. But to confirm its existence, we'll need to measure the atmosphere directly. A new mission concept was recently unveiled called the Venus Explorer for Reduced Vapours in the Environment (VERVE). It's a CubeSat that could fly with ESA's EnVision mission in 2031, studying the atmosphere for more evidence of active biology.
Lunar Astronauts Could Eat "Moon Rice"
If we can learn to grow our own food in space, it'll make surviving off Earth less challenging. While plants do grow in space, some genetic improvements are in order. Researchers have unveiled "Moon rice," a genetically manipulated strain of rice that grows much shorter than even dwarf varieties of rice and could be grown reliably in space. They're also simulating microgravity, constantly rotating the rice in all directions to see how it responds.
