Jupiter In Ultraviolet

This newly released image from the NASA Hubble Space Telescope shows the planet Jupiter in a color composite of ultraviolet wavelengths. Released in honor of Jupiter reaching opposition, which occurs when the planet and the Sun are in opposite sides of the sky, this view of the gas giant planet includes the iconic, massive storm called the “Great Red Spot.” Though the storm appears red to the human eye, in this ultraviolet image it appears darker because high altitude haze particles absorb light at these wavelengths. The reddish, wavy polar hazes are absorbing slightly less of this light due to differences in either particle size, composition, or altitude.

Happy 32nd Birthday to Hubble

Happy 32nd Birthday to the best telescope ever! Look at all this amazing activity going on in one tiny little sliver of our universe.

JWST will soon be bringing us even more astonishing images, but Hubble continues to carry the torch in spectacular fashion. Hubble has inspired 3 decades of space lovers, and we will forever be so grateful.

Happy 31st Birthday, Hubble

This video is absolutely stunning, and not *just* because it features one of my favorite places in space: https://youtu.be/vkFe4_wjRlY

Fun Hubble facts:

Launched on April 24, 1990, NASA's Hubble Space Telescope has made more than 1.5 million observations of about 48,000 celestial objects.

Hubble observations have produced more than 169 terabytes of data, which are available for present and future generations of researchers.

Astronomers using Hubble data have published more than 18,000 scientific papers, with more than 900 of those papers published in 2020.

NGC 2841

It is one of the more massive galaxies known. A mere 46 million light-years distant, spiral galaxy NGC 2841 can be found in the northern constellation of Ursa Major. This sharp view of the gorgeous island universe shows off a striking yellow nucleus and galactic disk. Dust lanes, small, pink star-forming regions, and young blue star clusters are embedded in the patchy, tightly wound spiral arms. In contrast, many other spirals exhibit grand, sweeping arms with large star-forming regions. NGC 2841 has a diameter of over 150,000 light-years, even larger than our own Milky Way. The featured composite image merges exposures from the orbiting 2.4-meter Hubble Space Telescope and the ground-based 8.2-meter Subaru Telescope. X-ray images suggest that resulting winds and stellar explosions create plumes of hot gas extending into a halo around NGC 2841.

The Majesty of NGC 4414

Way back in 1995, Hubble took this image of spiral galaxy NGC 4414 as part of the HST Key Project on the Extragalactic Distance Scale. An international team of astronomers, led by Dr. Wendy Freedman of the Observatories of the Carnegie Institution of Washington, observed this galaxy on 13 different occasions over the course of two months.

Images were obtained with Hubble's Wide Field Planetary Camera 2 (WFPC2) through three different colour filters. Based on their discovery and careful brightness measurements of variable stars in NGC 4414, the Key Project astronomers were able to make an accurate determination of the distance to the galaxy.

The galaxy’s central region contains older and more red and yellow stars. In the spiral arms, stars are being born all the time, and therefore these arms contain more blue stars - and also large amounts of dust.

The Beauty of NGC 2275

Look at this gorgeous galaxy! (courtesy of Hubble). And what a striking galactic core. I think I can almost spot the Siyane cruising in from the bottom right to investigate.

"NGC 2275 is classified as a flocculent spiral galaxy, located 67 million light-years away in the constellation of Cancer. Millions of bright, young, blue stars shine in the complex, feather-like spiral arms, interlaced with dark lanes of dust. Complexes of these hot, blue stars are thought to trigger star formation in nearby gas clouds. The overall feather-like spiral patterns of the arms are then formed by shearing of the gas clouds as the galaxy rotates."

Hubble Captures Globular Cluster NGC 6441

The Hubble Space Telescope has delivered another outstanding image. This one is of NGC 6441, a massive globular cluster in the constellation Scorpius. It’s one of the most massive ones in the Milky Way, and the stars in it have a combined mass of 1.6 million solar masses.

NGC 6441 is a gorgeous visual spectacle. It’s also of great scientific interest; it hosts four pulsars, an abnormally high number of variable stars, and has a rather high metallicity for a globular cluster. And it’s host to several Type II Cepheid stars, which is unusual for a cluster with high metallicity.

Happy 30th Anniversary, Hubble!

Happy 30th Anniversary to the Hubble Space Telescope! Hubble has done more than any mission or instrument to bring the wonder and majesty of space to generations of people. The JWST is going to have a lot to live up to if it wants to ever match Hubble's legend.🌟🌟🌟

"NASA is celebrating the Hubble Space Telescope's 30 years of unlocking the beauty and mystery of space by unveiling a stunning new portrait of a firestorm of starbirth in a neighboring galaxy.

In this Hubble portrait, the giant red nebula (NGC 2014) and its smaller blue neighbor (NGC 2020) are part of a vast star-forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, located 163,000 light-years away. The image is nicknamed the "Cosmic Reef," because it resembles an undersea world."

Is This the Biggest Spiral Galaxy in the Universe?

We're probably not in a position to judge on the UNIVERSE scale, granted. But it's definitely BIG. 4x wider than the Milky Way, in fact.

One thing that caught my eye about this article is how it brings home the scale of the universe. In Amaranthe, the Asterions' Gennisi Galaxy (aka Messier 94) is 5 megaparsecs from the Milky Way, and that feels like a long way away. Using superluminal (but not wormhole) propulsion, it took the Asterions 200 years to reach it.

UGC 2885, though, is SEVENTY megaparsecs away, and it's referred to in the article as "close by." Which, when you're talking about the universe, it is. #boggle 😱

It also strikes me as a decent location for the Rasu homeworld...🤔

The Great Red Spot

This new Hubble Space Telescope view of Jupiter, taken on June 27, 2019, reveals the giant planet's trademark Great Red Spot, and a more intense color palette in the clouds swirling in Jupiter's turbulent atmosphere than seen in previous years. The colors, and their changes, provide important clues to ongoing processes in Jupiter's atmosphere. More info: https://www.nasa.gov/feature/goddard/2019/hubble-new-portrait-of-jupiter

Hubble Deep-Sky Mosaic

Via NASA: “This might be the most exciting “history book” we’ve ever read. Astronomers have put together the largest and most comprehensive image of the evolving universe — using 16 years’ worth of observations from Hubble. Take a peek at this deep-sky mosaic.” https://www.nasa.gov/feature/goddard/2019/hubble-astronomers-assemble-wide-view-of-the-evolving-universe

Make sure and check out the short video at the link for a mind-boggling sense of scale.

Triangulum Galaxy

“Hubble takes gigantic image of the Triangulum Galaxy”: https://www.spacetelescope.org/news/heic1901.

“The NASA/ESA Hubble Space Telescope has captured the most detailed image yet of a close neighbour of the Milky Way — the Triangulum Galaxy, a spiral galaxy located at a distance of only three million light-years. This panoramic survey of the third-largest galaxy in our Local Group of galaxies provides a mesmerising view of the 40 billion stars that make up one of the most distant objects visible to the naked eye.”

One of those 40 billion stars, of course, is host to the Kats’ homeworld, Katoikia :D.
