We were scheduled to get 2 observations today for the HST active galaxy snapshot imaging program, but it looks like one of them didn't happen: probably a guide star acquisition failure. Here's the one that did get taken. This is SWIFT J0838.4-3557 (aka Fairall 1146).
#Hubble #astronomy

Here are two #Hubble images taken for snapshot program 15444 in the past week. These are active galaxies SWIFT J0138.6-4001 and SWIFT J2250.7-0854.

A new #Hubble image taken today for program 15444. This is the active galaxy SWIFT J0544.4+5909 (redshift 0.067).

These images from Hubble show the evolution of the bright spots on the inner ring around SN 1987A.

After the initial flash of UV radiation, the rings cooled down until they got hit by the shock wave of material ejected by the SN, which compress and heat the gas in the ring, making it glow. Spots started to dim again after 2011.

This image of SN 1987A was taken by Hubble in 1990, 3.5 years after the explosion.

The SN was about 0.1 light years in diameter then but the ring radius was estimated at ~0.75 ly.

Scientists speculated that the gas ring was created by the progenitor star 10K years ago. The ring material was ionized and heated by the intense flash of ionizing radiation from the supernova which must have reached the ring within a year after the explosion.

Here is a #Hubble image of the SN 1987A remnant. We see the same faint, hourglass-shaped rings, pearl necklace-like inner ring of clumps of gas and keyhole shape in the center. What we don't see in this visible-light view are a lot of the other structures in the inner ring that we see with JWST's infrared eyes.

Exploring Io's Volcanic Activity via Hubble and Webb Telescopes

Jupiter's moon Io, is the most volcanically active place in the Solar System, with continuous eruptions dotting its surface. We've gotten some new images from Juno during its recent flyby, but even more discoveries will come with JWST and Hubble analysis. The two famous space telescopes will be teaming up to look at the larger space environment around Io and Jupiter as Juno continues its flybys of the volcanic moon.

For context, here is the JWST near-infrared image superimposed on a #Hubble image of M51. The JWST images cover just a portion of the entire galaxy.

The Whirlpool Galaxy is a grand design spiral. Its arms may be so prominent because of a series of close encounters with NGC 5195, the small, yellowish galaxy behind the outermost tip of one of its arms.

@andreabettini riusciamo a vedere galassie lontane "milioni di anni luce" ma non riusciamo a fare una foto nitida e chiara di oggetti sulla Luna. #Hubble, #Webb

Here are two new #Hubble snapshot images of active galaxies taken on Tuesday for program 15444: SWIFT J1210.1-4637 and SWIFT J2258.9+4054. These are the first HST observations of these galaxies.

I am pretty sure everyone already seen an #image of the #Ring #Nebula, especially the one from the #Hubble #space #telescope (right below).

But have you seen the same #picture, from #JWST (left below) ?

Well, now you have 😉

There are so much more details, this is fantastic ! 🤩

The #Hubble view of the Ring Nebula.

The bright ring that gives the nebula its name is made of about 20,000 individual clumps of dense molecular hydrogen gas, each of them about as massive as the Earth.

If we could see the question mark in more detail, it might look like this #Hubble image of the merging galaxies II Zw 96. The distorted shape is created when the galaxies pass by each other as they merge, pulling on each other with gravity.

📆 Aug 11, 2023 #NASA calls for the #amateur #astronomical community : #Observers 🔭 on #Earth can measure the distribution of bright features on #Uranus 🪐 or #Neptune. They can also track those features much longer ⏱️ than either #spacecraft. The #Hubble images will be made available in late September at #MAST *
