Every time I get the digital “why can’t you scientists just look at the data” lecture, I wonder what people think scientists do. All we do is look at data including accelerating rate of expansion of the Universe…
Dec 22nd: More (Failed) Observations of Dark Matter
This week EVSN look at the upcoming solar maximum, how solar activity affects Neptune, the robotic invasion fleet on Mars, and how some of the weirdest star systems in reality have been able to form. In our closer look, we fail to see dark matter.
Sep 13th: Milky Way’s Stellar Streams Highlight Dark Matter
Recent observations of twelve different stellar streams around the Milky Way have revealed the effects of dark matter, similar to how lights on a Christmas Tree reveal the shape of the tree in dark.
Sep 4th: Questions: An Unlocked Moon, Energy Into Black Holes, & the Space Station’s Orbit
This week we find out what would happen if the Moon was rotating fast and not tidally locked to the Earth also where the light and matter go into a black hole.
Jul 24th: Student Questions: Curtis High School
Besides dark matter and dark energy, is there any possibility there’s anything else in outer space? What are the possibilities that white holes are really out there? More with @AstronomyCast
Jul 14th: Mystery of Ultra Diffuse Galaxy with NO Dark Matter Solved
May 22nd: Ultra-Diffuse Galaxies & Dark Matter
Astronomers first noticed the strange behaviors of rotating galaxies almost 100 years ago, suggesting there’s an invisible dark matter hold them together with gravity. Now astronomers have found examples of galaxies that are almost entirely made of dark matter. Does this tell us anything?
Jan 6th: Dr. Eddie Schwieterman Discusses Nitrous Oxide as a Biosignature
Why nitrous oxide or laughing gas can be included as a biosignature gas? Also evidence for MOND as dark matter, dark nebulae, eruption of Io, and how to get the cosmonauts home?
Oct 21st: NICER Maps a Neutron Star with Zaven Arzoumanian & Keith Gendreau
Pulsars have baffled scientists for decades, including how they work and what form matter takes within a pulsar. This week This week @WSHcrew join by Dr. Zaven Arzoumanian and Dr. Keith Gendreau that mapped J0030. And more news update.
Jul 5th: What are the Alternatives to Dark Matter?
What are some of the problems with dark matter? What about modified gravity? Are there any other solutions? I discuss these questions and more in today’s Ask a Spaceman!
