13 years on Venus is almost the equivalent of 8 years on Earth. It makes for a very interesting pattern.

We just got an unprecedented look at a black hole ripping apart a star

For the first time ever, astronomers got a close-up peek at a black hole ripping apart a star, a rare event that results in some of the star’s material getting ejected out into space. To research this phenomenon, astronomers used data from a tidal disruption that happened 3.9 billion years ago. Studying tidal disruptions like this one is revealing new information about how black holes behave.

!!!!!WHAT!!!! THE FUCK!!!! WHAT THE FUCK!!! THIS IS SO COOL!!!!

Holy shit. Where are my space nerds? My Star Trek nerds? @outside-the-government @bkwrm523 @feelmyroarrrr

Whoa.

@luninosity

Oooh. Totally neat. (And Chris and Seb would love it too!)

Today we celebrate International Women’s Day, a day in which we honor and recognize the contributions of women…both on Earth and in space.

Since the beginning, women have been essential to the progression and success of
America’s space program.

Throughout history, women have had to
overcome struggles in the workplace. The victories for gender rights were not
achieved easily or quickly, and our work is not done.

Today, we strive to make
sure that our legacy of inclusion and excellence lives on.

We have a long-standing cultural commitment
to excellence that is largely driven by data, including data about our people.
And our data shows progress is driven by questioning our assumptions and
cultural prejudices – by embracing and nurturing all talent we have available,
regardless of gender, race or other protected status, to build a workforce as
diverse as our mission. This is how we, as a nation, will take the next giant
leap in exploration.

As a world leader in science, aeronautics,
space exploration and technology, we have a diverse mission that demands talent
from every corner of America, and every walk of life.

So, join us today, and every day, as we
continue our legacy of inclusion and excellence.

Happy International Women’s Day!

This is actually really exciting??

#science #i don’t remotely understand this (via @ambientcrows)

Okay, that’s fine! You are actually not alone, I just fumbled through explaining this to some friends! I only just found this today so I may not be 100% accurate, if anyone knows better they can correct as needed!

Basically what the current theory of gravity (the theory of relativity) says is that gravity is a fundamental reaction. Gravity is what happens when spacetime curves around mass/energy- that curving causes two objects to move toward one another in space.

The problem is that the general theory of relativity doesn’t explain quantum physics. It cannot explain why the outside edges of galaxies goes zoom in ways they should not, unless there is an unknown factor. Until now, Science was like okay, what if Dark Matter and Dark Energy are a thing, where Dark Energy is what causes the universe to expand and Dark Matter is matter we can’t see, and actually haven’t even proved exists yet. Like, we’re literally making that shit up because nothing else we had made sense, and assuming that Dark Matter exists and is affected by gravity in ways which would explain the zoom allowed us to move on with theorizing things. Which was fine.

But then this guy, Erik Verlinde, comes along and is like okay but what if we go back and assume that our understanding of gravity is what’s wrong?

What if instead of gravity happening (spacetime moves and that movement causes gravity to happen), gravity emerges (the fabric of the universe has gravity stored inside its structure and spacetime and gravity emerge together from that structure). As its own thing, alongside spacetime (which is also a product of the structure of the universe), with its own behaviors and stuff.

And emergent gravity CAN explain why the edges of galaxies go zoom (I do not understand the math behind it I’m sorry!), without needing to rely on “idk let’s say Dark Matter and move on.” Already it’s allowed Verlinde to accurately predict the movement of stars on the edges of galaxies on its own. (of course, bear in mind that it does not explain EVERYTHING. yet. but it does bring physics and quantum physics closer to being able to work together).

Which makes all of this actually really cool, because it means that this huge assumption we humans have made and based a lot of stuff on for a while (dark matter existing) may be wrong, BUT we may have figured out WHY it was wrong, and that means we may be able to start doing things right, and that always leads to even more fascinating discoveries and advancements in science.

ufo-the-truth-is-out-there:

A star created 1,800 years ago after the collision of two distant suns is set to appear in the night sky for the first time – as the light from the crash finally reaches the Earth. 

Scientists predict that for six months in 2022, stargazers will be able to witness the birth of the new star, by fixing their telescopes near the Pisces and Cygnus constellations. Dubbed the Boom Star, it has taken nearly two millennia for its light to reach earth — where it will be able to be seen by the naked eye. Astronomers expect the collision to increase the brightness of the pair ten thousand fold, making it one of the brightest stars in the heaven for a time. The explosion, known as a Red Nova, will then dissipate and the star will remain visible in our skies as a single bright, but duller, dot. 

You’re not going to want to miss this appear in our sky as it’s a once in a lifetime event!     More here and here and here

some of my favourite absolutely SICK facts about the trappist-1 exoplanets:
- theyre all very close to one another and to their star, so the length of a year on them varies from 1 to 20 DAYS
- since they’re so close, the star appears a lot bigger than our sun from earth, and from one planet you could easily see the rest, some would even appear bigger than the moon from earth. you could literally see the surface of another planet with a naked eye!!!
- they’re tidally locked to their star like our moon is locked to earth, meaning only one side of a planet ever faces the star, and on the other side it’s always night. the sun never sets or rises on any of the planets
- the star is red, so the sunlight is red/orange, meaning if, for example, plants were to grow there, they could be black
and that’s just what we know now, imagine how much cool stuff we have yet to discover about the trappist-1 system

mindblowingscience:

Primitive plants are the latest forms of Earth life to show they can survive in the harshness of space, and for many months. Cold-loving algae from the Arctic Circle have joined the space-travelling club, alongside bacteria, lichens and even simple animals called tardigrades.

Preliminary studies of the algae after their return to Earth from the International Space Station lend some weight to the “panspermia” theory, that comets and meteorites could potentially deliver life to otherwise sterile planets. The results also provide insights into the potential for human colonies on distant planets to grow crops brought from Earth.

The algae were of the Sphaerocystis species, codenamed CCCryo 101-99, and were returned to Earth in June last year after spending 530 days on a panel outside the ISS. While space-borne, they withstood the vacuum, temperatures ranging from -20 °C at night to 47.2 °C during the day, plus perpetual ultraviolet radiation of a strength that would destroy most life on Earth if not filtered out by the atmosphere.

“I’m sure that plants of many kinds have been on the ISS before, but on the inside, not the outside,” says Thomas Leya of the Fraunhofer Institute for Cell Therapy and Immunology in Potsdam, Germany, who organised the algae experiment. “As far as I know, this is the first report of plants exposed on the surface of the space station.”
