Thought experiment: two #telescopes one at Alpha Centari pointed towards #Earth and one here at Earth pointed towards the view screen of the AC telescope. The Alpha Centari #telescope view screen would display an image of Earth from approximately 4 years ago. But would the Earth telescope see that image or one from approximately 8 years ago? #space #cosmology #science #Physics #4yeartelescope #astronomy #astrophysics #8yeartelescope #seethepast

Melotte 31 is an open star cluster located in the direction of the constellation Auriga. It is surrounded by very popular large nebulae, such as IC 405 and IC 410. Although it is classified as a stellar cluster, Melotte 31 is probably an asterism, a group of stars that coincidentally and from our perspective draw a peculiar shape or align in a.....

Earth has a newly discovered quasi-moon, 2023 FW13, that orbits the Sun in rhythm with us. It's small ("between a boxcar and a large Winnebago"), but an intriguing target for future exploration.

Giovanni Domenico Cassini was born #OTD in 1625.
He discovered four satellites of the planet Saturn and noted the division of the rings of Saturn; the Cassini Division was named after him. via @wikipedia
He is considered the greatest observational astronomer (of the 17th century) after Kepler and Galileo.

How much did the heavy rains help California's water crisis? @nasa NASA's GRACE-FO satellite has the answer.
The greatest net gain of water in nearly 22 years. Think of the state’s Central Valley region as a giant swimming pool: GRACE-FO measures all the water contained in the lakes, rivers, soil, snowpack, and underground aquifers. Winter storms raised levels about 20 inches.

Here is our attempt to study the formation of Mega Radio Halos with cosmological simulations - work led by Luca Beduzzi (master student at Uni PD)

Bottom line:
the formation of this new class of giant radio objects appears compatible with the continuous turbulent re-acceleration of fossil electrons, operating on Gyr timescales.

Now is a good time to check out the strawberry moon in southeast Michigan.
I went to our local grade school playfield a few minutes ago to see the moon in the southeast sky. Amazing to see moon details with binoculars.
Tonight's full moon is called the strawberry moon, for strawberry harvest.
In the metro Detroit area tonight, you'll be able to see Venus in the WNW sky with the naked eye.
Mars is also visible a bit to the west and slightly above Venus, though not as bright.
Full moon rises around 9:40pm in the southeast.
Should be great viewing with tonight's cooler temperatures!
