This new NASA/ESA Hubble Space Telescope image shows the Lagoon Nebula, an object with a deceptively tranquil name. The region is filled with intense winds from hot stars, churning funnels of gas, and energetic star formation, all embedded within an intricate haze of gas and pitch-dark dust.
In May 2010, a South African amateur astronomer pointed his telescope toward nearby galaxy NGC 300 and discovered what appeared to be a supernova — a massive star ending its life in a blaze of glory. However, SN 2010da is what we call a ‘supernova impostor’ — something initially thought to be a supernova, but later releaved as a massive star showing an enormous flare of activity.
International teams of astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) to explore the distant corner of the universe first revealed in the iconic images of the Hubble Ultra Deep Field (HUDF). These new ALMA observations are significantly deeper and sharper than previous surveys at millimetre wavelengths.
This image of the spiral galaxy NGC 3274 comes courtesy of the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 (WFC3). Hubble’s WFC3 vision spreads from the ultraviolet light through to the near infrared, allowing astronomers to study a wide range of targets, from nearby star formation through to galaxies in the most remote regions of the cosmos.
