Beautiful animations/simulations of light passing through a virtual telescope. Found in a blog post by Brian Koberlein. (Ok, the second one isn't a telescope.)

The blue bubble is a Wolf Rayet nebula around WR 152. Somewhere in this image is the planetary nebula IPHASX J221117.9+552841.0, which is near the open cluster NGC 7226.

Road to the Milky Way at La Silla
ESO Picture of the Week | 2016 Mar 07

In this picture, our home galaxy the Milky Way stretches across the sky above the landscape of the Chilean Andes. In the foreground, the roads of ESO’s La Silla Observatory are packed with state-of-the-art astronomical telescopes pointing towards, and far beyond, the Milky Way.

Several multinational telescopes are captured in this frame. The ESO 3.6-metre telescope stands on the central pedestal and is mounted with the High Accuracy Radial velocity Planet Searcher (HARPS) — the best exoplanet finder on Earth. Just next to the main dome, the smaller one once hosted the Coudé Auxiliary Telescope (CAT) which used to feed the powerful Coudé Echelle Spectrograph; they are now both decommissioned. At the foot of this pedestal lies the French Rapid Action Telescope for Transient Objects (TAROT) which follows up on highly energetic events called gamma-ray bursts. These are also studied by the Swiss 1.2-metre Leonhard Euler Telescope in the dome on the left, but its focus lies on the search for exoplanets.

Further out in the right, one can spot the Swedish–ESO Submillimetre Telescope (SEST) that was decommissioned in 2003 and replaced by the Atacama Pathfinder EXperiment telescope (APEX) on the Chajnantor Plateau. A map of all the La Silla facilities can be found here.

The high density of instruments on the roads of La Silla shows how desirable this location is for astronomical observations. It is far from brightly lit cities — the dramatic effect of dim brake lights of a single car can be seen on the left — and lies at a high altitude. ...

Swimming in Sculptor (Abell 2744)
ESA Hubble Picture of the Week | 2016 Mar 07

Peering deep into the early Universe, this picturesque parallel field observation from the NASA/ESA Hubble Space Telescope reveals thousands of colourful galaxies swimming in the inky blackness of space. A few foreground stars from our own galaxy, the Milky Way, are also visible.

In October 2013 Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS) began observing this portion of sky as part of the Frontier Fields programme. This spectacular skyscape was captured during the study of the giant galaxy cluster Abell 2744, otherwise known as Pandora’s Box. While one of Hubble’s cameras concentrated on Abell 2744, the other camera viewed this adjacent patch of sky near to the cluster.

Containing countless galaxies of various ages, shapes and sizes, this parallel field observation is nearly as deep as the Hubble Ultra-Deep Field. In addition to showcasing the stunning beauty of the deep Universe in incredible detail, this parallel field — when compared to other deep fields — will help astronomers understand how similar the Universe looks in different directions.

La Silla Dawn Kisses the Milky Way
ESO Picture of the Week | 2016 Mar 14

[img3="Credit: ESO/Babak Tafreshi (TWAN)"]http://cdn.eso.org/images/screen/potw1611a.jpg[/img3][hr][/hr]

This picture was taken just before dawn at the La Silla Observatory, in outskirts of the Chilean Atacama Desert. A layer of orange hovering over the horizon announces the imminent arrival of the Sun. These first hints of daylight are kissed by the Milky Way, which stretches out across the entire night sky. This view of our home galaxy is covered with dark patches, formed from dust particles blocking the light behind them.

In front of this cosmic scenery you can see some of the observatory’s telescopes. The closest is the Swedish–ESO Submillimetre Telescope (SEST), whose dish measures 15 metres across. It was decommissioned in 2003 and replaced by the Atacama Pathfinder EXperiment telescope (APEX) and the Atacama Large Millimeter/submillimeter Array (ALMA). On the plateau in the background stands the ESO 3.6-metre telescope, with the Coudé Auxiliary Telescope (CAT) right behind it.

SEST seems to be pointing at an extremely bright object: This is Venus, one of our neighbouring planets. Venus is lit up by the Sun and outshines all of the stars in the night sky. The triangular white glow that reaches up from the horizon through Venus is called zodiacal light. Zodiacal light is sunlight scattered by dust in the ecliptic — the plane of Earth’s orbit around the Sun.

Disco Lights from a Galaxy Cluster (MACS J0717)
ESA Hubble Picture of the Week | 2016 Mar 14

[img3="Credit: NASA, ESA, CXC, NRAO/AUI/NSF, STScI, and R. van Weeren (CfA)

In October of 2013 Hubble kicked off the Frontier Fields programme, a three-year series of observations aiming to produce the deepest ever views of the Universe. The project’s targets comprise six massive galaxy clusters, enormous collections of hundreds or even thousands of galaxies. These structures are the largest gravitationally-bound objects in the cosmos.

One of the Frontier Fields targets is shown in this new image: MACS J0717.5+3745, or MACS J0717 for short. MACS J0717 is located about 5.4 billion light-years away from Earth, in the constellation of Auriga (The Charioteer). It is one of the most complex galaxy clusters known; rather than being a single cluster, it is actually the result of four galaxy clusters colliding.

This image is a combination of observations from the NASA/ESA Hubble Space Telescope (showing the galaxies and stars), the NASA Chandra X-ray Observatory (diffuse emission in blue), and the NRAO Jansky Very Large Array (diffuse emission in pink). The Hubble data were collected as part of the Frontier Fields programme mentioned above.

Together, the three datasets produce a unique new view of MACS J0717. The Hubble data reveal galaxies both within the cluster and far behind it, and the Chandra observations show bright pockets of scorching gas — heated to millions of degrees. The data collected by the Jansky Very Large Array trace the radio emission within the cluster, enormous shock waves — similar to sonic booms — that were triggered by the violent merger.

That's just incredible.

I guess that the four colliding clusters form the shape that looks like a man sitting down. But there is also a compact source that emits two enormous and incredibly straight jets. Is anything known about that source?

Some people consider this to be a triplet (excluding NGC 7552 to the left).
