Planets is that the majority were born with hydrogen dominated atmospheresĪnd that a fraction lost these atmospheres due to photo evaporative driven Many of these planets are so low density that the only way to explain their current structure is that they host large, but low mass Not predicted by our early planet formation models conditioned on explaining Majority of stars hosting at least one of these planets. The last decade has taught us exoplanets with radii between 1 and4Įarth radii and orbital periods < 100 days are extremely common, with the Those unable to attend the colloquium in person are invited to participate online through Zoom (Meeting ID: 942 0262 2849, passcode 792771) using the link: This talk willĬover how this was accomplished, details of the first results, as well as futureĭirections that will enable real-time black hole movies. Million solar mass black hole in the center of the Milky way. This was followed up on May 12th, 2022 by the first image of, SgrA*, the 4 That confirms the theory of General Relativity at the boundary of a black hole. Hole in galaxy M87, and we have seen the predicted strong gravitational lensing Global network of radio dishes we have imaged the 6.5 billion solar mass black On April 10th, 2019, the EHT project reported success: using a Radiation emitted by infalling hot gas is lensed by the extreme gravity near theĮvent horizon. Observer should see a ring of light encircling the black hole, which forms when Einstein's theories predict that a distant Until recently, no one had ever seen whatĪ black hole actually looked like. Black holes are cosmic objects so small and dense, that nothing, not even lightĬan escape their gravitational pull.
