IC 2497 is a former quasar, whose light lit up Hanny's Voorwerp, which is now a light echo of that extinct quasar. It is about 45,000–70,000 light-years (14,000–21,000 pc) away from Hanny's Voorwerp. The quasar shut down sometime in the last 70,000 years. IC 2497: A Black Hole Story Told by a Cosmic Blob and Bubble. Hanny's Voorwerp, a cloud of gas, is glowing due to radiation from the giant black hole at the center of the galaxy IC 2497. Astronomers think the giant black hole in IC 2497 used to power a quasar in the past, but has faded in the last 200,000 years.

Below it is a once-mysterious 22 Oct 2019 As IC 2497 is a CT AGN, then it may have the more extended X-ray emission seen in many other obscured AGNs along the outflow axis (e.g., Caption.

The system composed by HV and its galaxy is therefore a great laboratory to study AGN variability on previously inaccessible time-scales. The analysis of the galaxy allows us to study the present state of the AGN and the AGN-host galaxy inter-
In the new study, researchers report that Hubble's cameras have uncovered star birth in a region of Hanny's Voorwerp that faces the spiral galaxy IC 2497, which is about 650 million light-years
IC 2497 (također poznat kao IRAS 09380+3457 i PGC 165538) je spiralna galaksija koja je udaljena oko 692 miliona sg od Zemlje i nalazi se u sazviježđu Mali lav. Najveći prečnik je 0,60 (121 hiljada sg) a najmanji 0,3 uglovnih minuta (60 hiljada sg). Prvo otkriće je napravio Stephane Javelle 14.
