30 Doradus, located in the heart of the Tarantula nebula, is the brightest star-forming region in our galactic neighborhood. It is home to several million young stars; among which live the most massive stars ever seen. The nebula resides 170,000 light-years away in the Large Magellanic Cloud, a small, satellite galaxy of our Milky Way. No known star-forming region in our galaxy is as large or as prolific as 30 Doradus.
A Montage of the Carina Nebula
The Carina Nebula (known by astronomers as NGC 3372) is sometimes called the Great Nebula in Carina or the Grand Nebula. These images taken by the Hubble space telescope show the magnificent structure within the Carina Nebula. These images contain regions of dense star formation, interstellar winds, massive particle clouds and much more. Many of these structures are hundreds of light-years across and make the size of our solar system look pathetic in comparison. The Carine Nebula is about 10,000 light-years away from earth and is located in the constellation Carina.

A Cosmic Necklace Larger than a Solar System
The “Necklace Nebula”, also called PN G054.2-03.4, is the exploded aftermath of a giant star that came too close to its Sun-like binary companion. The two stars that produced the Necklace Nebula live in a relatively small orbit about each other. They have a period of 1.2 days and a separation on the order of 5 times the radius of the Sun.

Spotted today on a very startorial BridgeUp STEM Helen Fellow at @amnhnyc: cosmic/nebula/galaxy/space @vans that look like a real astronomical image to me, but I can’t quite place it… Thor’s Helmet nebula? Musca planetary nebula? Help!!!
They aren’t on the Vans website, but they are available online at places like Shoe Carnival and DSW, and they are super cool in person. I might have to make room in my closet next to my cosmic Converse!

Hi I’m kaijuno and my favorite hobby is tilt shifting and colorizing photos of space
I’ve been working on editing space images into “space porn”, specifically working with tilt shift. The photos were taken by Hubble but I processed and edited them into what they look like now. I emailed them to my old astro prof who thought they were “ethereal and god damn gorgeous” so I thought I’d post them lol

Literally the biggest thing I got out of my 2 year college physics classes (apart from thinking about friction whenever I drive and the vast loneliness of space) was how stupid astrology is
Like day one of my astronomy 101 in freshman year my prof went on a tirade about how astronomy should have been given the name “astrology” because astrology in latin is essentially “study of the stars” while astronomy is something along the lines of “physical universe beyond our atmosphere” and we had to pick that because the idk whoever did astrology first were hogging the title
This doesn’t look like much, but these are RR Lyrae variable stars! They’re 10,500 light years way! I took about half of these pictures, and my classmates took the other half. I took the data and ran it through a few Python programs and made them into a gif! The observing period here was unfortunately only about 2 hours, but we got some good data!
The two stars here that are RR Lyrae variable stars are V* BH Peg and V* BG Peg (circled in the image below, BH Peg is the top star and BG Peg is the bottom).
RR Lyrae Variable stars are stars that are nearing the end of their life, and their luminosity changes periodically. There are non-RR Lyrae Variable stars that can have periods of years, or they may fluctuate irregularly.
RR Lyraes are really cool though! RR Lyraes are pulsating aging stars with a mass of around half the Sun’s. They’re thought to have previously shed mass during the Red-Giant Branch phase, and consequently, they were once stars with similar or slightly less mass than the Sun. Because of this, they’re super easy to use to gauge distances in our galaxy and local globular clusters (blobs of stars). But what’s even crazier is that they have periods of between 40 and 0.3 days. That’s super fast, cosmically speaking!
Oh! and the bottom star is an Eclipsing Binary! That means that one blob is actually two stars, and because of our vantage point from earth, they cross in front of each other!
V* BH Peg has a period of 0.6 days, and V* BG Peg has a period of 1.9 days.
