Hubble Captures an Elusive Galaxy Cluster

Astronomers at MIT and elsewhere have observed infrared signs of the closest tidal disruption event (TDE) to date. A bright flare was detected from the galaxy NGC 7392 in 2015 (top left panel). Observations of the same galaxy were taken in 2010-2011 (top right), prior to the TDE. The bottom left shows the difference between the first two images, representing the actual, detected TDE. For comparison, the bottom right panel shows the same galaxy in the optical waveband. CREDIT Courtesy of Christos Panagiotou, et al

Illustration of the current Fluidic Telescope’s (FLUTE’s) concept for a next-generation large space observatory. The space telescope’s mirror would be created in space from liquid materials and would be approximately 164 feet (50 meters) in diameter – half as long as a football field. The optics would be shaped by the natural surface tension force exerted by fluids. Credits: NASA

Astronomers Double Number Of Known Repeating Fast Radio Bursts

This image shows the jet and shadow of the black hole at the centre of the M87 galaxy together for the first time. The observations were obtained with telescopes from the Global Millimetre VLBI Array (GMVA), the Atacama Large Millimeter/submillimeter Array (ALMA), of which ESO is a partner, and the Greenland Telescope. This image gives scientists the context needed to understand how the powerful jet is formed. The new observations also revealed that the black hole’s ring, shown here in the inset, is 50% larger than the ring observed at shorter radio wavelengths by the Event Horizon Telescope (EHT). This suggests that in the new image we see more of the material that is falling towards the black hole than what we could see with the EHT. CREDIT R.-S. Lu (SHAO), E. Ros (MPIfR), S.

The seven galaxies highlighted in this James Webb Space Telescope image have been confirmed to be at a distance that astronomers refer to as redshift 7.9, which correlates to 650 million years after the big bang. This makes them the earliest galaxies yet to be spectroscopically confirmed as part of a developing cluster. Credits: NASA, ESA, CSA, T. Morishita (IPAC). Image processing: A. Pagan (STScI)
