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.
Are there more than four forces of nature? Is dark matter connected to dark energy? What the heck are dark photons? I discuss these questions and more in today’s Ask a Spaceman!
On today’s #spaceradio, @PaulMattSutter will discuss about SpaceX, whether we find evidence for a parallel universe, what if we reached the edge on the universe, dark matter’s shape, and lets learn how to die in space
Join @PaulMattSutter in #spaceradio as he will discuss about the edge of the Milky Way, will we ever understand dark matter? What happens in a particle collision? How can we see the CMB?
Is the universe alive? more at #365DaysOfAstro
In astronomy ‘dark’ is the polite way to describe wild speculation.
