Remember Zoozve? The quasi-moon of Venus featured on Radiolab that was named after a typo on a map of the Solar System?
Now is your chance to name one of Earth’s quasi-moons. The IAU and Radiolab are holding a contest — they will pick the top 10 names, which then go to a popular vote.
1/4 "All those protoplanetary discs will be lost, like tears in a rain of ultraviolet photons."
Ok, it doesn't sound as cool as the actual quote, but still 😉
This tear-shaped object is a protoplanetary disc –the birthplace of planets around another star– observed with ESO's Very Large Telescope. Material from the disc is being stripped away by a bright star beyond the upper-right corner, outside of the field of view, hence this cometary shape.
Happy June! Together, the Hubble and Spitzer space telescopes present a colorful view of the Orion Nebula’s dynamic star-forming environment in ultraviolet, infrared, and visible light. Credit: NASA, ESA, STscI. #astronomy
Seeking new data, the James Webb Space Telescope is observing objects that are old acquaintances to the Hubble Space Telescope. Magic Universe proposes a slow transition of the images of both devices in orbit to better see what is new in Webb's latest observations, activate this transition by placing the mouse over the image or clicking on touch screens. The objective of..... #astronomy#space#astrophysics#astrophotography
It's #MilkyWay season again here in the northern hemisphere.
I took this image using my phone last night around 2am looking south from my moderately light-polluted site in east Tucson. 5×90s subs captured in Astroshader were combined in Siril. A final stretch was applied in GIMP.
Further experiments last night. Here, I doubled the total exposure time (so, a total of 900 s). Same processing steps.
Having started in astrophotography about a million years ago using film, it blows my mind that my phone can collect the data used to make an image like this now.
The excellent collaboration image between astronomers Mark Hanso and Martin Pugh shows the peculiar planetary nebula HFG-2, also cataloged as PK 247-04 1 among other designations. It is a sphere with a network-shaped structure, whose filaments connect with each other and shows a possible opening to the south. This planetary nebula appears to be..... #astronomy#space#astrophysics#astrophotography
When I was born, we still didn't have evidence that there were planets around other suns. Now you can observe them in your backyard. That's pretty amazing, if you ask me!
#Astronomy has another case of "#Bullshit circles the planet before the truth gets its shoes on" - A recent paper looked for #DysonSpheres by finding red stars which coincided with radio emission. The hype resulted in a thousand news articles... except a new paper shows they failed to check whether normal red M-dwarf stars might happen to be close to normal radio sources (radio-loud AGN) 🤦♂️ https://arxiv.org/abs/2405.14921
Now we'll be lucky if this good science gets 10% the press that the original did.
@mattkenworthy@ExoHugh That feels like it could use an asterisk pointing to a note below saying something like: "It could be aliens but to show that you need the shiniest double plus gold standard evidence to prove that."
This image shows the regions surrounding the Corona star cluster, better known by its English name, Coronet Cluster. Also cataloged as R CrA for its brightest star, it is located at a distance of about 400 light years from the Solar System and is located in the direction of the Corona Australis Constellation, isolated on the edge of the Gould Belt. The Corona Cluster is..... #astronomy#space#astrophysics#astrophotography
A solar eclipse occurs, as predicted by the Greek philosopher & scientist Thales, while Alyattes is battling Cyaxares in the Battle of the Eclipse, leading to a truce.
How exactly Thales predicted the eclipse remains uncertain; some scholars assert the eclipse was never predicted at all. Others have argued for different dates, but only the eclipse of May 585 BC matches the conditions of visibility necessary to explain the historical event.
My Harvard Horizons video is now on YouTube! I worked hard on this with some talented animators, really excited to share it with ya'll :)
This is a short, public talk of my research: exploring connections between galaxies and cosmology with @desisurvey. https://www.youtube.com/watch?v=BIB0F_oNxdM
In this villa near Florence, Italy, Galileo Galilei spent the last decade or so of his life under house arrest. I was there this weekend on the panel of a science outreach event, here's the video recording in Italian:
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).
