![]() ![]() They used a tool on the Keck II telescope called the Deep Imaging Multi-Object Spectrograph (DEIMOS) to study the movement of stars in the galaxy. To investigate the amount of dark matter in Dragonfly 44, the team turned to one of the largest telescopes on Earth, located at the W. They suspected that dark matter was responsible for holding the galaxy together, and this particular galaxy seemed like it contained a ton of it, so they set out to determine exactly how much. There wouldn't be enough gravity, and the stars would drift apart. Van Dokkum and his team later realized that there was something very odd about Dragonfly 44: a galaxy that big couldn't possibly hold itself together with so few stars. While it's as big as the Milky Way, it only emits about 1 percent as much light. Dragonfly 44 was one of the largest and brightest galaxies they found. ![]() But no one had noticed these galaxies hiding in the dark before. This distance is easily close enough for a telescope to see the Hubble Space Telescope can see billions of light-years away. ĭragonfly 44 is one of 47 ultradiffuse, or "fluffy" galaxies that Pieter van Dokkum of Yale University and colleagues found in the Coma Cluster, a group of at least 1,000 galaxies around 300 million light-years from Earth. With a combination of eight telephoto lenses and cameras, the array is designed to look at objects in space that aren't bright enough to see with other telescopes. This dark galaxy, named Dragonfly 44, was first detected in 2015, through the use of the Dragonfly Telephoto Array in New Mexico. Whatever it may be, about 80 percent of the mass in the universe is dark matter. ![]() No one really knows what dark matter is made of, but scientists believe it exists because they can see the effects of its gravity on other things in space. The other 99.99 percent of the stuff in this galaxy can't be seen. Only one-hundredth of one percent of the galaxy is ordinary, visible matter like stars and planets. I'm just not sure that it's financially feasible to use this stuff long term.Astronomers have discovered a galaxy as big as the Milky Way that consists almost entirely of dark matter, a mysterious and invisible substance that scientists have been trying to figure out for decades. if you have a scalp condition that you're trying to treat, and would rather not ingest medicines with crazy side-effects, or use Rx creams that leave you with super grease-head (like my mom has been doing), I think this is a good alternative, and that you'll see results. it hasn't been long enough for me to speak to the claims that it stimulates new hair growth. the difference with using Awaken as compared to the other shampoo bar was almost instantly noticeable. before this, I'd been using a shampoo bar that contained mint, tea tree and rosemary to help with this newly developed scalp condition, and it helped somewhat. I'm actually feeling hopeful that with continued use the rash may go away completely, but it's too soon to say. the redness/itchiness has definitely decreased. after only 2 weeks of using these products every other day, the rash on my scalp is noticeably less. I do like how it leaves my scalp feeling cool and tingly. I should get a year's worth of hair care products for nearly $100 with shipping. the bottles are small compared to other brands, and the cost of these products is prohibitive. maybe it's the condition? it's bonkers how thick it is - I have to use brute force to get it out of the bottle. once dry, my hair is so weighed down that I hesitate to use my normal styling products for fear my hair will be completely flat/lifeless. what I don't like is that my hair doesn't look/feel especially clean after I use these, I'm left with a thick residue on my hair that no amount of rinsing removes. ![]()
