Happy #ValentinesDay from Venus – the planet named for the goddess of love! 💖

Hubble captured this image in ultraviolet light back in 1995. Venus is the hottest planet in our solar system, with surface temperatures at about 900 degrees Fahrenheit! More: go.nasa.gov/3E7r36j

In the very middle of this #HubbleFriday image is a galaxy... but you might have to look very closely to find it.

The newly discovered dwarf galaxy Donatiello II is seen nestled among a smattering of distant stars and even more distant galaxies: go.nasa.gov/3DUC4bb

“Ring” in the start of a new spokes season!

On the planet Saturn, spokes are suspected to be caused by the interaction between the planet’s magnetic field and solar wind.

You can see two smudgy spokes on the rings on the left side of this new image: go.nasa.gov/3xcbdn2
#Hubble

It’s spokes season!

On Saturn, mysterious “spokes” appear on its rings near the planet’s seasonal equinoxes.

Scientists suspect they are caused by Saturn’s magnetic field interacting with solar wind from the Sun, but this hypothesis is unconfirmed: go.nasa.gov/3RN8SZd
#Hubble

Can you spot six of Uranus’s moons in this picture? Look closely 🔍

This #HubbleClassic image shows Uranus’ faint rings and some of its moons.

The bright spot in the lower right is Ariel, which has the brightest surface of all of the planet's moons: go.nasa.gov/3IaxU1y
#Hubble

Welcome to a "star factory"!

This #HubbleFriday view shows the Tarantula Nebula, the brightest region of starbirth in our galactic neighborhood.

About 161,000 light-years away, it's within the Large Magellanic Cloud – a satellite galaxy to our Milky Way: go.nasa.gov/3RsBMOh
#Hubble

Happy #GroundhogDay!

Punxsutawney Phil saw his shadow this morning... and from up in space, Hubble can see shadows too!

This image shows three of Jupiter’s dozens of moons – and two of their shadows – moving across the planet in 2015: go.nasa.gov/3HTQJWg
#Hubble

With Hubble, astronomers measured the mass of a single, isolated white dwarf – which is the surviving core of a burned-out star.

The white dwarf, called LAWD 37, is 56% the mass of our Sun: go.nasa.gov/3l31XyZ

More ⬇️
#Hubble

Astronomers were able to determine this using “gravitational microlensing” – when the gravity of a foreground object warps the light coming from an object behind it.

The light from a background star was slightly deflected by the gravitational warping of space by LAWD 37.

The cosmic ocean 🌊

This #HubbleClassic image shows a sea of glowing hydrogen gas, along with small amounts of other elements such as oxygen and sulfur.

Known as M17 (or the Swan or Omega Nebula), this starforming region resides 5,500 light-years away: go.nasa.gov/3ReWzVr

⏪ #FlashbackFriday to Hubble’s observations of Comet ISON in April 2013!

Even without a space-based observatory to help, this comet became visible with the naked eye too!

#Hubble

Another comet viewing opportunity is here: C/2022 E3 (ZTF) can be seen with binoculars or a small telescope in the predawn sky as the comet travels across the northern sky.

Check your favorite skywatching app for the comet's position and more info! go.nasa.gov/3Y27Dax

Have a stellar #HubbleFriday!

This week's image shows the bright star V 372 Orionis, along with a smaller companion star in the upper left.

Both stars call the Orion Nebula home – which is a massive region of starbirth about 1,450 light-years away: go.nasa.gov/3DkX6zq

Ever wonder what Hubble saw on your birthday?

Here’s what Hubble captured #OTD in 2000 – the galaxy NGC 4013, seen edge-on from 55 million light-years away!

Galaxies galore!

This #HubbleClassic image shows Abell 1689, which is one of the most massive clusters of galaxies known to exist.

Abell 1689 is made up of so much matter that it warps light traveling to us from objects located behind the galaxy cluster: go.nasa.gov/3j1NTFe
#Hubble

A cosmic treasure trove! 🤩

This #HubbleFriday contains lots of astronomical marvels: the hazy galaxy UGC 7983, more distant galaxies, and even an asteroid, seen as four streaks of light on the upper left (from four exposures taken by Hubble).

This nebula’s weather forecast? 200,000 degrees Celsius! 🔥

That’s the surface temperature of the dying star at the center of the nebula NGC 2440.

It’s shedding outer layers of material to create the complex structure seen in this #HubbleClassic image: go.nasa.gov/3HcVbzo

Happy #HubbleFriday!

This week's image shows a galactic gathering. On the right, the faint, sparse galaxy LEDA 48062 shines from 30 million light-years away. On the left is a more sharply defined galaxy called UGC 8603: go.nasa.gov/3XaJ9ff

News from #AAS241!

Hubble recorded a star's final moments as it was ripped apart and eaten up by a black hole – getting twisted into a donut-like shape in the process.

Stars across the spectrum! ⭐

These two views of NGC 346 show a dynamic, massive star-forming region in the Small Magellanic Cloud, which is a satellite galaxy to our own Milky Way.

What's going on in NGC 346?
#Hubble

The Hubble view (above on the left) shows NGC 346 in visible and near-infrared light. Outflows and radiation from young stars are wearing away at the denser outer portions of the region!

M81 is one of the brightest galaxies in the night sky!

Seen in this #HubbleClassic view, M81 resides about 11.6 million light-years away. It's home to a black hole about 15 times the mass of our Milky Way Galaxy’s central black hole!
