Make It A "Black (Hole) Friday," NASA Style!

NASA's positive take on Black Friday: Black Hole Friday!

In general, I agree with the sentiment; let's shift our focus!

...Shift gears from thinking "out of the red and into the black" on Black Friday...

...To focus more on appreciating the awe inspiring things in this amazing universe of ours!
RED SHIFT! BLUE SHIFT! BLACK HOLES!
Yeah, I'm in!
Let's make it a Black Hole Friday instead!

from NASA.gov:
"In this artist's illustration, turbulent winds of gas swirl around a black hole. Some of the gas is spiraling inward toward the black hole, but another part is blown away.
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.
How Big Are Black Holes?
Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or "stuff," in an object."

Saturn's Moon Titan Has Lakes... That Aren't Really Water... And One Is Named Kraken...

Titan's the name of a moon of Saturn, so it's pretty "titanic," if you get my drift.
It's also ice cold and would kill you, just like the boat.
BUT!! you'll have a great chance of enjoying watching THIS "titanic" video whether you're male OR female!

Video Credit: Cassini Radar Mapper, JPL, USGS, ESA, NASA
Explanation via NASA APOD: What would it look like to fly over Titan? Radar images from NASA's robotic Cassini satellite in orbit around Saturn have been digitally compiled to simulate such a flight. Cassini has swooped past Saturn's cloudiest moon several times since it arrived at the ringed planet in 2004. The virtual flight featured here shows numerous lakes colored black and mountainous terrain colored tan. Surface regions without detailed vertical information appear more flat, while sufficiently mapped regions have their heights digitally stretched. Among the basins visualized is Kraken Mare, Titan's largest lake which spans over 1,000 kilometers long.
Titan's lakes are different from Earth's lakes in that they are composed of hydrocarbons with similarities to liquid natural gas. How Titan's lakes were created and why they survive continues to be a topic of research.
