One of my favourite geology facts is this: These diagrams are a lie.
The mantle isn’t yellow. Nor is it orange, or red, or brown, or gray, or black.
The earth’s mantle is made up largely of peridotite.
The earth’s mantle is lime green.
The existence of large numbers of molecules in winds powered by supermassive black holes at the centers of galaxies has puzzled astronomers since they were discovered more than a decade ago. Molecules trace the coldest parts of space, and black holes are the most energetic phenomena in the universe, so finding molecules in black hole winds was like discovering ice in a furnace.
Astronomers questioned how anything could survive the heat of the energetic outflows, but a new theory from researchers in Northwestern University’s Center for Interdisciplinary Research and Exploration in Astrophysics (CIERA) predicts that these molecules are not survivors at all, but brand-new molecules, born in the winds with unique properties that enable them to adapt to and thrive in the hostile environment.

Fascinating, even if you are unable to grasp the mathematical depths, details are for professional thinkers on the field, enjoy the surface, is pretty enjoyable too.

I have seen many “Space achievements 2015” articles and posts leaving international accomplisments completely out, so here are some of them:
China National Space Administration’s Chang’e-3 landed on the Moon on 14 December 2013, becoming the first spacecraft to soft-land since the Soviet Union‘s Luna 24 in 1976.
It became the first true “lifting body” vehicle, which reached a near-orbital speed and then returned back to Earth without any help from wings.
Japan Aerospace eXploration Agency’s Akatsuki is the first spacecraft to explore Venus since the ESA’s Venus Express reached the end of its mission in 2014.
Rosetta spacecraft, the first to drop a lander (named Philae) on a comet, entered orbit around 67P in 2014 and continues to orbit the body. On June 13, European Space Operations Centre in Darmstadt, Germany, received signals from the Philae lander after months of silence.

Ok, so I don’t know how I ended up here and woah!
they made
characters
for
every
single
element
of the
periodic
table!
And also they made this
and this
*new ship*
There’s even a granny!
It’s like
superheros
(there’s a guy who looks like Hulk btw)
and humans
and there are
twins!!
And Bethoveen
THEY MADE THOR
And there’s also this which made me laugh
I can’t!

We don’t have any real pictures of the Milky Way galaxy. Most non-illustrated images of the entire Milky Way spiral are actually of another spiral galaxy called Messier 74. It’s impossible to take a full photo of the Milky Way’s spiral structure because it’s about 100,000 light-years across, and we’re stuck on the inside. Source Source 2 Source 3
Bruh this is some sci-fi shit. Fucking time crystals
Happy TRAPPIST-1 Day!
Here’s a comic on our latest discovery!
