The SOMBRERO GALAXY is an unbarred spiral galaxy in the Virgo constellation. It is located 28 million light years from Earth.

It has a very bright nucleus and an unusually large bulge. The nucleus of a galaxy is located in the center, and the bulge is the “halo” of material/stars that are found around the nucleus. The shape of the bulge and the nucleus give the appearance of a sombrero.

There is a supermassive black hole located in the nucleus of this galaxy. Looking at the measured nearby galaxies, the Sombrero Galaxy has the largest black hole at its center. It is said that the mass of the black hole is 1 billion times the mass of the Sun.

Got any questions/facts about the Sombrero Galaxy? Send me a message and we can talk about it! Stay tuned for tomorrow’s galaxy!

Milky Way rising

ESA astronaut Tim Peake posted this stunning image on his social media channels, commenting: “Watching the Milky Way rising over the horizon”.

Tim’s six-month mission to the ISS is named Principia, after Isaac Newton’s ground-breaking Naturalis Principia Mathematica, which describes the principal laws of motion and gravity.

He is performing more than 30 scientific experiments for ESA and taking part in numerous others from ESA’s international partners.

Jupiter's Great Red Spot 'roars with heat'
Jupiter's giant storm is somehow heating the planet's upper atmosphere - possibly by means of sound waves - astronomers discover.

Jupiter’s Great Red Spot - a hurricane three times bigger than Earth - is blasting the planet’s upper atmosphere with heat, astronomers have found.

Using measurements from an infrared telescope in Hawaii, a UK and US team found evidence for temperatures as high as 1,500C - hundreds of degrees warmer than anywhere else on the planet.

They suggest the hotspot is created by thunderous soundwaves “breaking” in the thin upper reaches of the atmosphere.

The research is published in Nature.

It arguably solves what planetary scientists had dubbed an “energy crisis” for gas giants like Jupiter: temperatures in their upper atmospheres soar much higher than can be explained by solar energy - especially given their vast distances from the Sun.

If the mysterious heat were generated by local sources, like Jupiter’s famous storm, then the conundrum would be solved - and these measurements are the first direct evidence of any such activity.

Study co-author Dr Tom Stallard, from the University of Leicester, said this was a major step forward in a “20-30 year odyssey” to try and understand heat flow on Jupiter.

“Ever since Voyager, we’ve had measurements of the temperature at the top of Jupiter’s atmosphere, and it’s been hot across the whole globe - from the poles, all the way to the equator,” he told the BBC.

M13: A Great Globular Cluster of Stars 

M13 is one of the most prominent and best known globular clusters. Visible with binoculars in the constellation of Hercules, M13 is frequently one of the first objects found by curious sky gazers seeking celestials wonders beyond normal human vision. M13 is a colossal home to over 100,000 stars, spans over 150 light years across, lies over 20,000 light years distant, and is over 12 billion years old.

At the 1974 dedication of Arecibo Observatory, a radio message about Earth was sent in the direction of M13. The featured image in HDR, taken through a small telescope, spans an angular size just larger than a full Moon, whereas the inset image, taken by Hubble Space Telescope, zooms in on the central 0.04 degrees.
