A Bright Find
ESA Hubble Picture of the Week | 2020 Jun 15
Seen here in incredible detail, thanks to the NASA/ESA Hubble Space Telescope, is the starburst galaxy formally known as
PLCK G045.1+61.1. The galaxy appears as multiple reddish dots near the center of the image and is being gravitationally lensed by a cluster of closer galaxies that are also visible in this image.
Gravitational lensing occurs when a large distribution of matter, such as a galaxy cluster, sits between Earth and a distant light source. As space is warped by massive objects, the light from the distant object bends as it travels to us. This effect was first predicted by Einstein’s
general theory of relativity.
From 2009 to 2013, the European Space Agency’s
Planck space observatory captured multiple all-sky surveys. In the course of these surveys, with complementary observations by the
Herschel Space Observatory, Planck discovered some of the brightest
gravitationally lensed high-
redshift galaxies in the night sky.
It was during the study of these Planck-Herschel selected sources using Hubble that the optical starlight emitted from this ultra-bright galaxy was found.

The Sco-Cen association

I love this image, which centers on the Sco-Cen association. An association of stars is one or more (related) clusters of stars that have come apart and move together across the sky as a very loose and scattered grouping. In the case of the Sco-Cen association, it looks like a confusion of B-type stars spread across the sky mostly in the constellations Scorpius, Lupus, Centaurus and Crux, at a distance of ~380-470 light-years. The blue B-type stars here are 11-15 million years old. Oh yes, red supergiant Antares also belongs to the Sco-Cen association.
I wonder what it was that set off this mighty wave of star formation.
The Sco-Cen association is the nearest association of OB stars to the Sun. Read about the Sco-Cen association

ESO: Oasis in the Desert (Paranal Residencia)

Oasis in the Desert
ESO Picture of the Week | 2020 Jun 22
The onset of early morning reveals the ESO
Residencia hotel, where astronomers and engineers stay while working with the ESO telescopes at the
Paranal Observatory in Chile’s Atacama Desert. These telescopes include the Very Large Telescope (
VLT), the VLT Survey Telescope (
VST) — which are visible in the background — and
VISTA (Visible and Infrared Survey Telescope for Astronomy).
Because of the arid desert that surrounds it, the
Residencia is sometimes called an “oasis in the desert”. The scenery is so striking that the building was featured in the 2008 James Bond film
Quantum of Solace. The views from the western side of the Residencia towards the Pacific Ocean are spectacular, and the architecture itself is also award-winning.
Guests staying at the Residencia are well provided for, with over a hundred bedrooms, a restaurant, a swimming pool and even a sauna available. There is also an artificial garden that acts as a refuge from some of the harshest weather conditions on Earth, including extreme dryness, high winds, intense sunlight and large temperature fluctuations.
ESO’s latest and most ambitious project, the Extremely Large Telescope (
ELT), is being built nearby at Cerro Armazones and the Residencia will also serve the scientists and engineers working there.
HEIC: A Galaxy on Edge (NGC 5907)

A Galaxy on Edge
ESA Hubble Picture of the Week | 2020 Jun 22
The galaxy known as
NGC 5907 stretches wide across this image. Appearing as an elongated line of stars and dark dust, the galaxy is categorised as a
spiral galaxy just like our own Milky Way. In this new image from the NASA/ESA Hubble Space Telescope, we don’t see the beautiful spiral arms because we are viewing it edge-on, like looking at the rim of a plate. It is for this reason that
NGC 5907 is also known as the Knife Edge Galaxy.
The Knife Edge Galaxy is about 50 million light-years from Earth, lying in the northern constellation of
Draco. Although not visible in this image,
ghostly streams of stars on large arching loops extend into space, circling around the galaxy; they are believed to be remnants of a small
dwarf galaxy, torn apart by the Knife Edge Galaxy and merged with it over four billion years ago.

Forming Betelgeuse from a Stellar Merger
AAS Nova Featured Image | 2020 Jun 23
This image from a simulation shows how the the large, red supergiant star Betelgeuse may have been created by the tidal disruption and merger of a binary star within the past few hundred thousand years. Betelgeuse — a prominent star in our night sky — has recently made headlines due to its unexpected, sudden dimming and rebrightening. But the supergiant has other quirks, like how it’s hurtling rapidly through space as a “runaway” star, or how it spins unusually fast for its size. A team of Louisiana State University researchers led by Manos Chatzopoulos has now performed simulations that show that Betelgeuse’s odd properties could be explained if the supergiant was formed by the merger of an unequal-mass binary star system in the relatively recent past. To learn more about the authors’ results, check out the original article.

ESO: Memory of the Solar Eclipse above La Silla

Memory of the Solar Eclipse above La Silla
ESO Picture of the Week | 2020 Jun 29
On 2 July 2019, ESO’s
La Silla Observatory was host to a rare astronomical event, a total
solar eclipse. Inaugurated in 1969, La Silla Observatory led ESO to the front line of astronomical science. The
50th anniversary last year celebrated La Silla’s continued contribution to science, and coincided fortuitously with the shadow of the total solar eclipse, or
umbra, passing over the site.
Captured in this image is the stunning view of the total solar eclipse, a rare event which lasted for less than two minutes that day. During a total solar eclipse, the Sun and Moon cross paths in the sky, overlapping perfectly, a feat only possible because the Sun and Moon happen to be the right distance from the Earth to take up the same portion of the sky.
A few stars shine bright for a moment while the Sun’s brilliant corona halos the Moon, like shimmering strands of silk. A truly breathtaking experience, one that will not occur again at La Silla until the year 2231.

Birds of a Feather
ESA Hubble Picture of the Week | 2020 Jun 29
The spiral pattern shown by the galaxy in this image from the NASA/ESA Hubble Space Telescope is striking because of its delicate, feathery nature. These "
flocculent" spiral arms indicate that the recent history of star formation of the galaxy, known as
NGC 2775, has been relatively quiet. There is virtually no star formation in the central part of the galaxy, which is dominated by an unusually large and relatively empty galactic bulge, where all the gas was converted into stars long ago.
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. The spiral nature of flocculents stands in contrast to the
grand design spirals, which have prominent, well defined-spiral arms.

IF THE DAYWAY WAS SEEN DURING THE DAY
The evolution of cameras, sensors and other equipment is taking important steps, will we ever be able to photograph the milky way during the day?
In this image, taken during the day 20/05 at 14:20 and during the night on the day 21/05 at 2:20. This means that it would be the sky, approximate, disregarding the inclination of the earth, on 11/20.
