Whenever I mention dark matter in anyway in the Guide to Space, or in a questions show, I get a bunch of responses that have essentially the same point. Astronomers are just speculating, why do they even think dark matter is a thing?
Time for @AwesomeAstroPod news round-up and skyguide. We have JWST, new type of nebula, detecting life in Europa, exoplanet around dead star, galaxy with no dark matter and more. #365DaysOfAstro
Knowledge moves forward, and so, we must move with it. Today we’ll give you an update on some of the most fascinating, fast-changing topics in astronomy, astrophysics and cosmology.
Today Travelers in the Night Sky discuss about how to preserve the night sky and the invisible material that speed up galaxies.
As galaxies in a cluster slam into each other and the surrounding matter, they create bow shocks, causing movement of the plasma around these clusters. With the maps provided by the high-energy jets coming out of black holes, the task can be a little easier.
This week we are very excited to welcome Dr. Chanda Prescod-Weinstein to talk about her book THE DISORDERED COSMOS: A Journey into Dark Matter, Spacetime, and Dreams Deferred, and news update about the helicopter on Mars.
You’ve probably heard of dark matter and dark energy, but maybe you don’t fully understand what they are. Or maybe the idea itself just rubs you the wrong way and you’d like to know why scientists think they can just make stuff up like this. So you’d like to overturn cosmology? Here’s all you need to do.
A new study proposed that supermassive black holes could form directly from dark matter in high density regions near the centers of galaxies, possibly explaining how these monsters came into existence early in our universe.
Weekly update will provides info about a galaxy that stripped its dark matter, formation of the moon, Hayabusa 2 sample arrival, Chang’e 5, and a discussion with Casey Dreier from @exploreplanets
Time for weekly news roundup. This week @WSHCrew will talk about Venus, dark matter gravitational lensing, and diamond planets.
