Rebooting the Jamshid meme I made for my Daevabad read through bc I would die for Saze
The universe is full of dazzling sights, but there’s an eerie side of space, too. Nestled between the stars, shadowy figures lurk unseen. The entire galaxy could even be considered a graveyard, full of long-dead stars. And it’s not just the Milky Way – the whole universe is a bit like one giant haunted house! Our Nancy Grace Roman Space Telescope will illuminate all kinds of spine-chilling cosmic mysteries when it launches in 2027, but for now settle in for some true, scary space stories.
One of the first signs that things are about to get creepy in a scary movie is when the lights start to flicker. That happens all the time in space, too! But instead of being a sinister omen, it can help us find planets circling other stars.
Roman will stare toward the heart of our galaxy and watch to see when pairs of stars appear to align in the sky. When that happens, the nearer star – and orbiting planets – can lens light from the farther star, creating a brief brightening. That’s because every massive object warps the fabric of space-time, changing the path light takes when it passes close by. Roman could find around 1,000 planets using this technique, which is called microlensing.
The mission will also see little flickers when planets cross in front of their host star as they orbit and temporarily dim the light we receive from the star. Roman could find an additional 100,000 planets this way!
Roman is going to be one of the best ghost hunters in the galaxy! Since microlensing relies on an object’s gravity, not its light, it can find all kinds of invisible specters drifting through the Milky Way. That includes rogue planets, which roam the galaxy alone instead of orbiting a star…
…and solo stellar-mass black holes, which we can usually only find when they have a visible companion, like a star. Astronomers think there should be 100 million of these black holes in our galaxy.
Black holes aren’t the only dead stars hiding in the sky. When stars that aren’t quite massive enough to form black holes run out of fuel, they blast away their outer layers and become neutron stars. These stellar cores are the densest material we can directly observe. One sugar cube of neutron star material would weigh about 1 billion tons (or 1 trillion kilograms) on Earth! Roman will be able to detect when these extreme objects collide.
Smaller stars like our Sun have less dramatic fates. After they run out of fuel, they swell up and shrug off their outer layers until only a small, hot core called a white dwarf remains. Those outer layers may be recycled into later generations of stars and planets. Roman will explore regions where new stars are bursting to life, possibly containing the remnants of such dead stars.
If we zoom out far enough, the structure of space looks like a giant cobweb! The cosmic web is the large-scale backbone of the universe, made up mainly of a mysterious substance known as dark matter and laced with gas, upon which galaxies are built. Roman will find precise distances for more than 10 million galaxies to map the structure of the cosmos, helping astronomers figure out why the expansion of the universe is speeding up.

Just wanna say something
I know this fandom is small compared to the other book fandoms, but what I TRULY LOVE about ours is that all of us know each other. Every time one of us posted something about Lockwood & Co, all of us instantly liked, reblogged, and sometimes comment. No accounts being left out with only one like, no one ignores anyone. Like, this is the only fandom where I feel safest and most comfortable in
So, yeah, shout out to us for creating this little paradise
will wood song names are so funny they're always like "The Tree Test of Amsterdam: You Can Turn Maple Syrup Into Cocaine unless you ask to be or not to be a.k.a Werewolf Transgenderism in B Minor after a long rainstorm at Niagara Falls a.k.a The Frat Boy Anti-Anthem / trying to swallow an entire nuclear warhead is ultimately a fruitless endeavour [The Most Fruitful Endeavour is Danny Devito's Newest Action Blockbuster] a.k.a So What's the Deal With Airline Food - The Last Will and Old Testament of Jerry 'The God Killer' Seinfeld a.k.a The Last Rocky Road Ice Cream On Earth versus The Great Silicon Valley Disaster a.k.a Fast Times at Whatever High School You Went To a.k.a That Bush Is On Fire! (אֶהְיֶה אֲשֶׁר אֶהְיֶה) a.k.a I'm Getting Tired" and you hit play and it's one of the best songs you've ever heard in your life.
I’m sorry but this is the only way I can picture The End

Hi I’m back from the dead and obsessed with moon knight, enjoy this one single post before I am drowned in the tidal wave of studying for finals
I’ve never been a huge MCU fan but i could write a 10 page essay on how much I love this show and I probably will
The fact that I had a Kane chronicles/egyptian mythology phase in middle school has nothing to do with this whatsoever
