May 2022 saw the first ever image of the supermassive black hole at the center of our galaxy-called Sagittarius A*-published by the Event Horizon Telescope (EHT).

In addition to other facilities, the EHT network of radio observatories that made this image possible includes the Atacama Large Millimeter/submillimeter Array (ALMA) and the Atacama Pathfinder EXperiment (APEX) in the Atacama Desert in Chile, co-owned and co-operated by ESO is a partner on behalf of its member states in Europe. The image of the Sgr A* black hole is an average of the different images the EHT Collaboration has extracted from its 2017 observations. The telescope is named after the event horizon, the boundary of the black hole beyond which no light can escape. It was captured by the Event Horizon Telescope (EHT), an array which linked together eight existing radio observatories across the planet to form a single Earth-sized virtual telescope. It's the first direct visual evidence of the presence of this black hole. The first image of Sgr A*, the supermassive black hole at the centre of our galaxy, with an added. Here a portion of the open cluster NGC 6530-4,350 light-years from Earth within the Lagoon Nebula in the constellation Sagittarius-appears as a roiling wall of smoke studded with stars. JWST may have gotten all the attention, but the Hubble Space Telescope continued to pump out incredible images in 2022. The new NASA/ESA/CSA James Webb Space Telescope’s unprecedented observational capabilities at infrared wavelengths will complement Hubble observations by allowing astronomers to peer through the dusty envelopes around newly born stars and investigate the faintest, earliest stages of starbirth. In particular, Hubble was crucial to investigations of the proplyds around newly born stars in the Orion Nebula. This makes understanding their origin and lifetimes in other astronomical environments challenging.Hubble’s ability to observe at infrared wavelengths - particularly with Wide Field Camera 3- have made it an indispensable tool for understanding starbirth and the origin of exoplanetary systems. The vast majority of proplyds have been found in only one region, the nearby Orion Nebula. They scoured the region in the hope of finding new examples of proplyds, a particular class of illuminated protoplanetary discs surrounding newborn stars. ![]() ![]() It is the nebula that gives this image its distinctly smokey appearance clouds of interstellar gas and dust stretch from one side of this image to the other.Astronomers investigated NGC 6530 using Hubble’s Advanced Camera for Surveys and Wide Field Planetary Camera 2. The cluster is set within the larger Lagoon Nebula, a gigantic interstellar cloud of gas and dust. ![]() NGC 6530 is a collection of several thousand stars lying around 4350 light-years from Earth in the constellation Sagittarius. image from the NASA/ESA Hubble Space Telescope.
