NASA Observation

This NASA/ESA Hubble Space Telescope image shows the spiral galaxy NGC 4845, located over 65 million light-years away in the constellation of Virgo (The Virgin). The galaxy’s orientation clearly reveals the galaxy’s striking spiral structure: a flat and dust-mottled disc surrounding a bright galactic bulge. NGC 4845’s glowing centre hosts a gigantic version of a black hole, known as a supermassive black hole. The presence of a black hole in a distant galaxy like NGC 4845 can be inferred from its effect on the galaxy’s innermost stars; these stars experience a strong gravitational pull from the black hole and whizz around the galaxy’s centre much faster than otherwise. From investigating the motion of these central stars, astronomers can estimate the mass of the central black hole — for NGC 4845 this is estimated to be hundreds of thousands times heavier than the Sun. This same technique was also used to discover the supermassive black hole at the centre of our own Milky Way — Sagittarius A* — which hits some four million times the mass of the Sun (potw1340a). The galactic core of NGC 4845 is not just supermassive, but also super-hungry. In 2013 researchers were observing another galaxy when they noticed a violent flare at the centre of NGC 4845. The flare came from the central black hole tearing up and feeding off an object many times more massive than Jupiter. A brown dwarf or a large planet simply strayed too close and was devoured by the hungry core of NGC 4845.

Scientific Background

This particular celestial object, Supermassive and super-hungry, was captured by NASA's deep space observatories. While its specific historical mythology remains a mystery, objects of this type are crucial for our understanding of cosmic evolution and stellar life cycles.

To observe phenomena similar to this, we recommend using high-contrast filters and a motorized equatorial mount.

Stargazer FAQ

Are the colors in this nebula image real?

NASA often uses 'false color' techniques. Scientists map invisible wavelengths (like infrared) or specific gases to visible colors (red, green, blue) to highlight the nebula's structural details.

Can I see this nebula with a standard telescope?

While some bright nebulas are visible with entry-level telescopes, capturing these stunning details usually requires deep-sky astrophotography equipment and long exposures.
