In 2015, researchers discovered a black hole named CID-947 that grew much more quickly than its host galaxy. The immense gravity of black holes also distorts space itself, so it is possible to see the influence of an invisible gravitational pull on stars and other objects. Matter is heated to millions of degrees as it is pulled toward the black hole, so it glows in X-rays. NASA's telescopes that study black holes are looking at the surrounding environments of the black holes, where there is material very close to the event horizon. No light of any kind, including X-rays, can escape from inside the event horizon of a black hole, the region beyond which there is no return. How can we learn about black holes if they trap light, and can't actually be seen? Image Credit: NASA/JPL-Caltech/Roma Tre Univ.ġ.
This supermassive black hole has been extensively studied due to its relatively close proximity to our galaxy. The X-ray light is coming from an active supermassive black hole, also known as a quasar, in the center of the galaxy.
High-energy X-rays (magenta) captured by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, are overlaid on visible-light images from both NASA's Hubble Space Telescope and the Sloan Digital Sky Survey. Now, this new program will allow you to adopt a plant for a fee of $10 to $20, with the option to donate more if you want, and the money will be used to create a floral arrangement that will go to a memory care unit in your name.Galaxy NGC 1068 is shown in visible light and X-rays in this composite image. Green says previously she'd been giving away these plants because they aren't in good enough shape to sell them, and just couldn't bear to throw them away. Through a collaborative conversation, we talked about how cool it would be for the people who know what they are doing with plants to be able to adopt them. We just got to talking and joked about how often this happens. Owner Ashley Green says she gets a lot of messages from customers and friends with questions about their dying plants, some have also been bringing her the plants in defeat.Ī friend of mine stopped in with one of her sad dying plants and she just dropped it off and had this look of defeat on her face and then walked away.
Cloud has begun a plant adoption program.
