ESO: Other Worlds (ALMA)

Other Worlds
ESO Picture of the Week | 2020 Jun 01
One of the most exhilarating results in modern astronomy is the knowledge that the Universe is full of worlds beyond our Solar System, known as exoplanets. Increasing evidence suggests that the majority of stars in the Universe have planets whizzing around them; one such system can be seen in this majestic Picture of the Week.

The antennas here are among the 66 that make up the Atacama Large Millimeter/submillimeter Array (ALMA), located on the Chajnantor plateau in Chile. Two bright stars sit directly above the centre antenna; the brightest of these two stars is a triple star system known as Alpha Centauri. An exoplanet named Proxima b was recently discovered orbiting within the habitable zone of one these three stars (Proxima Centauri) by ESO telescopes and other facilities. As Alpha Centauri is the closest star system to Earth, Proxima b is the closest exoplanet to Earth ever discovered.

Another world can be seen in this stunning sky — this time, one a little closer to home. At the top of the image, two bright, reddish objects sit just outside the main river of the Milky Way. The one on the left is Antares — a red giant star in Scorpius — and the one on the right is Saturn, the spectacular ringed gas giant planet.

HEIC: Stellar Snowflakes (NGC 6441)

Post by bystander » Mon Jun 01, 2020 2:32 pm

Stellar Snowflakes
ESA Hubble Picture of the Week | 2020 Jun 01
Almost like snowflakes, the stars of the globular cluster NGC 6441 sparkle peacefully in the night sky, about 13 000 light-years from the Milky Way’s galactic centre. Like snowflakes, the exact number of stars in such a cluster is difficult to discern. It is estimated that together the stars weigh 1.6 million times the mass of the Sun, making NGC 6441 one of the most massive and luminous globular clusters in the Milky Way.

NGC 6441 is host to four pulsars that each complete a single rotation in a few milliseconds. Also hidden within this cluster is JaFu 2, a planetary nebula. Despite its name, this has little to do with planets. A phase in the evolution of intermediate-mass stars, planetary nebulae last for only a few tens of thousands of years, the blink of an eye on astronomical timescales.

There are about 150 known globular clusters in the Milky Way. Globular clusters contain some of the first stars to be produced in a galaxy, but the details of their origins and evolution still elude astronomers.

M88

M88 is a very interesting galaxy.
Wikipedia wrote:

M88 is one of the fifteen Messier objects that belong to the nearby Virgo Cluster of galaxies. It is galaxy number 1401 in the Virgo Cluster Catalogue (VCC) of 2096 galaxies that are candidate members of the cluster.[5] M88 may be on a highly elliptical orbit that is carrying it toward the cluster center, which is occupied by the giant elliptical galaxy M87. It is currently 0.3–0.48 million parsecs from the center and will come closest to the core in about 200–300 million years. The motion of M88 through the intergalactic medium of the Virgo cluster is creating ram pressure that is stripping away the outer region of neutral hydrogen. This stripping has already been detected along the western, leading edge of the galaxy.
So although M88 has a rather small yellow center and an intricate set of dusty spiral arms, it is losing its gas and its ability to form new stars due to its motion through the intergalactic medium of the Virgo Cluster.

ESO: The UHD Universe (VLT)

Post by bystander » Mon Jun 08, 2020 4:08 pm

The UHD Universe
ESO Picture of the Week | 2020 Jun 08
n 2016, a team of four world-class astrophotographers and videographers journeyed to ESO’s Paranal Observatory in Chile. Their goal? To capture striking views of the Universe in ultra high definition (UHD) and fulldome formats — perfect for use in planetarium shows! Over the course of a few weeks, the photographers gathered UHD stills, fulldome timelapses, 360-degree panoramas, and more, including a whole host of breathtaking shots of their surroundings.

One such shot is this ESO Picture of the Week, which shows Paranal — home to ESO’s Very Large Telescope (VLT) — at night. The stargazer visible to the right of the frame, pointing to the beautiful arc of the Milky Way curving overhead, is ESO Photo Ambassador Babak Tafreshi, one of the aforementioned expedition members. The constituent telescopes of the VLT can be seen scattered across the left of the frame (the four boxy Unit Telescopes, and three of the four rounder Auxiliary Telescopes).

The products returned by ESO’s 2016 UHD Expedition are being used by the ESO Supernova Planetarium & Visitor Centre, which opened in May 2018. The ESO Supernova is a collaboration between ESO and the Heidelberg Institute for Theoretical Studies, and the building was donated by German foundation the Klaus Tschira Stiftung.

HEIC: One Amongst Millions (NGC 2608)

Post by bystander » Mon Jun 08, 2020 4:14 pm

One Amongst Millions
ESA Hubble Picture of the Week | 2020 Jun 08
Looking deep into the Universe, the NASA/ESA Hubble Space Telescope catches a passing glimpse of the numerous arm-like structures that sweep around this barred spiral galaxy, known as NGC 2608. Appearing as a slightly stretched, smaller version of our Milky Way, the peppered blue and red spiral arms are anchored together by the prominent horizontal central bar of the galaxy.

In Hubble photos, bright Milky Way stars will sometimes appear as pinpoints of light with prominent lens flares. A star with these features is seen in the lower right corner of the image, and another can be spotted just above the pale centre of the galaxy. The majority of the fainter points around NGC 2608, however, lack these features, and upon closer inspection they are revealed to be thousands of distant galaxies. NGC 2608 is just one among an uncountable number of kindred structures.

Similar expanses of galaxies can be observed in other Hubble images such as the Hubble Deep Field which recorded over 3000 galaxies in one field of view.

AAS: Fractals in Cosmic Gas

Post by bystander » Wed Jun 10, 2020 10:44 pm

Fractals in Cosmic Gas
AAS Featured Image | 2020 Jun 08
apjlab8d2cf1_hr[1].jpg
What happens in galactic and intergalactic settings when cold, dense gas moves through hot, diffuse gas? You can see the result in the complex simulations shown above (click for a closer look), as reported in a recent publication led by scientist Drummond Fielding (Center for Computational Astrophysics, Flatiron Institute). Turbulent mixing layers like those simulated by Fielding and collaborators form in a vast variety of cosmic environments: the interstellar medium, the circumgalactic medium, expanding supernova remnants, cosmic filaments, galactic winds, protoplanetary disks, the solar corona, and many more. The authors’ new models show the fractal nature of the cooling surface that arises within these layers as the gases mix.

You can watch the animated version of the simulation here, which shows how eight different fluid properties evolve over time in a turbulent layer containing mixing cold and hot gas. For more information, check out the original article, linked below.

ESO: Looking into Crystal-Clear Skies (La Silla)

Post by bystander » Mon Jun 15, 2020 4:20 pm

Looking into Crystal-Clear Skies
ESO Picture of the Week | 2020 Jun 15
ESO’s La Silla Observatory boasts a remarkably high number of cloud-free nights a year. The billions of stars that make up the Milky Way is a very common sight indeed. The dome shown in this image houses one of three 60-centimetre telescopes that make up the ExTrA project, which had its first light in late 2017.

This small group of telescopes is primarily designed to detect distant exoplanets transiting in front of bright and nearby red dwarf stars. The project aims to discover as many transiting planets as possible — including Earth-size planets in the habitable-zone — and to determine their structure and composition. These planets will then be observed by the world’s largest telescopes, in order to characterise their atmospheres.
