Panning over The Cometary Globule CG4

Panning over The Cometary Globule CG4 | ESO

The cometary globule CG4 glows menacingly, like the gaping mouth of a gigantic celestial creature, in this pan video based on an image from the European Southern Observatory’s Very Large Telescope. What looks huge and bright in this image is actually a faint nebula and not easy to observe. The exact nature of CG4 remains a mystery.

This zoom video sequence goes from a wide view of the southern Milky Way deep into the constellation of Puppis close to the site of the Vela supernova remnant. The final view shows a new close-up view of the cometary globule CG4. It glows menacingly, like the gaping mouth of a gigantic celestial creature, in this this new image from the European Southern Observatory’s Very Large Telescope (VLT). What looks huge and bright in this image is actually a faint nebula and not easy to observe. The exact nature of CG4 remains a mystery.

ALMA Explores Debris Disc Around Fomalhaut Star: A New Solar System? | ESO

ALMA Explores Debris Disc Around Fomalhaut Star: A New Solar System? | ESO

Fomalhaut is one of the brightest stars in the sky. At roughly 25 light-years away the star lies especially close to us, and can be seen shining brightly in the constellation of Piscis Austrinus (The Southern Fish). This image from the Atacama Large Millimeter/submillimeter Array (ALMA) shows Fomalhaut (center) encircled by a ring of dusty debris. This was the first time a scene like this was captured at such a high resolution and sensitivity at millimeter wavelengths.

Fomalhaut’s disc comprises a mix of cosmic dust and gas from comets in the Fomalhaut system (exocomets), released as the exocomets graze past and smash into one another. This turbulent environment resembles an early period in our own Solar System known as the Late Heavy Bombardment, which occurred approximately four billions years ago. This era saw huge numbers of rocky objects hurtle into the inner Solar System and collide with the young terrestrial planets, including Earth, where they formed a myriad of impact craters—many of which remain visible today on the surfaces of planets such as Mercury and Mars.

Fomalhaut is known to be surrounded by several discs of debris—the one visible in this ALMA image is the outermost one. The ring is approximately 20 billion kilometers from the central star and about 2 billion kilometers wide. Such a relative narrow, eccentric disc can only be produced by the gravitational influence of planets in the system, like Jupiter’s gravitational influence on our asteroid belt.

Zooming in on Fomalhaut Star and its Dusty Disc | ESO

This video sequence starts with a wide-field view of the sky around the star Fomalhaut in the constellation of Piscis Austrinus (The Southern Fish). Fomalhaut is the brightest star in the constellation and one of the brightest stars known to have an orbiting planet. It lies about 25 light-years from the Earth and is surrounded by a huge disc of dust.

The final view of this video shows a new Atacama Large Millimeter Array (ALMA) image of the disc (orange) and the new results from ALMA have given astronomers a major breakthrough in understanding a nearby planetary system and provided valuable clues about how such systems form and evolve.

Note that ALMA has so far only observed a part of the ring. The underlying blue picture shows an earlier picture obtained by the NASA/ESA Hubble Space Telescope.

Globular Cluster NGC 6540 | Hubble

Globular Cluster NGC 6540 | Hubble

This scintillating image showcases the globular cluster NGC 6540 in the constellation Sagittarius, which was captured by the NASA/European Space Agency Hubble Space Telescope’s Wide Field Camera 3 and Advanced Camera for Surveys. These two instruments have slightly different fields of view—which determines how large an area of sky each instrument captures. This composite image shows the star-studded area of sky that was captured in both instruments’ field of view.

NGC 6540 is a globular cluster, a stable, tightly bound multitude of stars. The populations of these clusters can range from tens of thousands to millions of stars, all of which are trapped in a closely-packed group by their mutual gravitational attraction.

Distance: about 17,000 light years

The brightest stars in this image are adorned with prominent cross-shaped patterns of light known as diffraction spikes. These astronomical embellishments are a type of imaging artefact, meaning that they are caused by the structure of Hubble rather than the stars themselves. The path taken by the starlight as it enters the telescope is slightly disturbed by its internal structure, causing bright objects to be surrounded by spikes of light.

Hubble peered into the heart of NGC 6540 to help astronomers measure the ages, shapes, and structures of globular clusters towards the center of the Milky Way. The gas and dust shrouding the center of our galaxy block some of the light from these clusters, as well as subtly changing the colors of their stars. Globular clusters contain insights into the earliest history of the Milky Way, and so studying them can help astronomers understand how our galaxy has evolved.

Close-up Pan of The Medusa Nebula | ESO

This close-up pan video shows the most detailed image ever taken of the Medusa Nebula (also known Abell 21 and Sharpless 2-274). It was captured using the European Southern Observatory’s Very Large Telescope (VLT) in Chile. As the star at the heart of this nebula made its final transition into retirement, it shed its outer layers into space, forming this colorful cloud. The image foreshadows the final fate of the Sun, which will eventually also become an object of this kind.

This pan video gives a close-up look at a spectacular group of young stars—the open star cluster NGC 3766 in the constellation of Centaurus (The Centaur).

Distance: 7,000 light years

Very careful observations of these stars by a group from the Geneva Observatory using the Swiss 1.2-meter Leonhard Euler Telescope at ESO's La Silla Observatory in Chile have shown that 36 of the stars are members of a new and unknown class of variable star.

Who Turned Off the Lights on Betelgeuse? | ESO

ESOcast 238 Light: When Betelgeuse, a bright orange star in the constellation of Orion, became visibly darker in late 2019 and early 2020, the astronomy community was puzzled. A team of astronomers have now published new research done with ESO's Very Large Telescope and Very Large Telescope interferometer that solves the mystery of Betelgeuse's dimming. This ESOcast Light summarizes the discovery.
