NGC 3310: A Starburst Spiral Galaxy.
The party is still going on in spiral galaxy NGC 3310. Roughly 100 million years ago, NGC 3310 likely collided with a smaller galaxy causing the large spiral galaxy to light up with a tremendous burst of star formation. The changing gravity during the collision created density waves that compressed existing clouds of gas and triggered the star-forming party. The featured image from the Gemini North Telescope shows the galaxy in great detail, color-coded so that pink highlights gas while white and blue highlight stars. Some of the star clusters in the galaxy are quite young, indicating that starburst galaxies may remain in star-burst mode for quite some time. NGC 3310 spans about 50,000 light years, lies about 50 million light years away, and is visible with a small telescope towards the constellation of Ursa Major.

The hot core of this dying star has a surface temperature of about 50,000 degrees Celsius and is ejecting its outer layers at roughly 6 million kilometers per hour! Eventually the remnant star will collapse, forming a white dwarf star!

M81 is a grand spiral galaxy located about 12 million light years from Earth. Near its center is a supermassive black hole roughly 70 million times more massive than our Sun, or about 17 times more massive than the black hole in the center of our Milky Way galaxy!

play_circle_filled Astronaut Bruce McCandless II Floats Free in Space 👨‍🚀
On Feb. 7, 1984, during the Space Shuttle Challenger’s STS-41B mission, NASA Astronaut Bruce McCandless II makes the first, untethered, free flight spacewalk in the Manned Maneuvering Unit.
👏 👏
• If given the chance, Would you do it?

Bruce: "I wanted to say something similar to Neil [Armstrong] when he landed on the moon, so I said, 'It may have been a small step for Neil, but it’s a heck of a big leap for me.' That loosened the tension a bit." Video credit: @nasa ...

The Homunculus Nebula is a bipolar emission and reflection nebula surrounding the massive star system Eta Carinae, about 7,500 light-years from Earth. The nebula is embedded within the much larger Carina Nebula, a large star-forming H region.⁣

#Uranus, named for the Greek god of the sky, was discovered on this day in 1781 by William Herschel! All of the other planets in our solar system (except Earth) were given names from Roman mythology. If Uranus had been named for the Roman god of the sky, we would know it as Caelus!

You are looking at the first ever image of a Black Hole. 🕳 💫
Astronomers at @esoastronomy @alma.observatory & APREX teamed up to observe and image the gargantuan Black Hole at the heart of Galaxy M87, 53 million light years away.
#RealBlackHole
The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun.
Congratulations again to all the #Astronomers that will be mentioned in our Stories later today.
History in the making!

The first REAL image of a black hole is being released on April 10 (tomorrow) by @alma.observatory and @esoastronomy🔥
All other photos of black holes have just been computer generated images (like the one in this post).
**The reveal will be at 9AM EST. You can watch it on the live stream, link in my bio**
It will be posted here so make sure to check your Instagram!.

play_circle_filled When neutron stars collide, the explosion can produce up to a billion times the energy of the luminosity of the all the stars in the Milky Way combined, for the 50 or so seconds it takes place.
The event ejects matter at 60,000 km per second or 20% the speed of light. This cosmic firework is called a Kilonova, responsible for the heavy elements like gold, platinum and uranium

This beauty is Galaxy UGC 1810.
It’s blue outer ring is likely a result of wild and violent gravitational interactions. This ring's blue color is caused by massive stars that are blue hot and have formed only in the past few million years. The inner galaxy appears older, redder, and threaded with cool filamentary dust. A few bright stars appear well in the foreground, unrelated to UGC 1810, while several galaxies are visible well in the background. Arp 273 lies about 300 million light years away toward the constellation of Andromeda. Quite likely, UGC 1810 will devour its galactic sidekick over the next billion years and settle into a classic spiral form.

play_circle_filled The Sound Two Black Holes Merging! ✨
The two merging black holes are each roughly 30 times the mass of the sun, with one slightly larger than the other. Time has been slowed down by a factor of about 100. The event took place 1.3 billion years ago. The incredibly powerful event, which released 50 times more energy than all the stars in the observable universe, lasted only fractions of a second.
This animation by  @caltechedu / @mitmedialab  shows the collision of two black holes, a tremendously powerful event detected for the first time ever by the Laser Interferometer Gravitational-Wave Observatory, or LIGO. LIGO detected gravitational waves, or ripples in space and time generated as the black holes spiraled in toward each other, collided, and merged.
Scientists used the SXS (Simulating eXtreme Spacetimes) project to animate the environment around the star.
