English amateur astronomer Richard Christopher Carrington was born #OTD in 1826.
In 1859 his astronomical observations demonstrated the existence of solar flares as well as suggesting their electrical influence upon the Earth & its aurorae; and whose 1863 records of sunspot observations revealed the differential rotation of the Sun. His publications include Results of Astronomical Observations Made at the Observatory of the University, Durham; & Observations of the Spots on the Sun.
This image taken by the Hubble Space Telescope shows spiral galaxy NGC 4689. Resembling a cosmic fingerprint, this galaxy exhibits spiral arms branching in all directions, classifying it as a foculating spiral. Its position facing us offers astronomers an almost perfect view to study its structure in detail. The disk contains dense regions of gas, dust and..... #astronomy#space#astrophysics#astrophotography
I taunt astronomers in other EM regimes because unlike us cool radio astro folks, they mostly can't do astronomy during the day (where we can).
Now, folks from our uni (Macquarie Uni) and fellow PhD'er Sarah Caddy, are building telescopes for daytime obs.
THIS IS BETELGEUSE IN THE DAY! 🤯
To get these results, we've built a telescope that has MANY eyes, and named it after the huge spider we have here called 'The Huntsman' (which of course, has many eyes).
The image by astronomer Jerome Yesavage shows a low surface brightness planetary nebula cataloged as PN Kohoutek 1-16, located in the direction of the Draco Constellation and located at a distance of about 3,400 light years from the Solar System. The central star is a very hot pulsating star called DS Dra, it has a magnitude of 14.96 and is of spectral type..... #astronomy#space#astrophysics#astrophotography
It's #WorldTurtleDay! In 1754 the English botanist and author John Hill proposed a new constellation he called "Testudo" (the Tortoise). It didn't catch on with astronomers, but under dark night skies it can still be seen. Read more about it: https://unchartedconstellations.com/
This is the Owl Nebula from last night. It is about 2000 light years away and about 2 light years in diameter. It formed about 8000 years ago from gases ejected from a star.
Finally, after months of work, the #ESAEuclid Early Release Observation images, data, first science results, and #Euclid mission reference papers have been released. You can read more in our blog post, which has links to the papers, the press releases, and everything else:
