The “Leo Trio” of galaxies

That massive sunspot group rivals the size of the one that triggered the Carrington Event in 1859. So far it has kicked off some large coronal mass ejections heading our way, but fortunately nothing on that scale. Let’s hope we just get some pretty auroras from this, and nothing more damaging!

That twisted-up galaxy at the top is NGC 3718. We don’t actually know if it’s a spiral or a lenticular galaxy, because the galaxy below it, NGC 3729, appears to have warped it beyond recognition when it passed by it. Also look for the cluster of five more distant galaxies just to the right of…

If you look at the constellation Orion in the winter night’s sky, the center of Orion’s “sword” is not a star at all – it is the brightest nebula in our sky, M42 or the Great Nebula of Orion. Sitting right on top of it is technically another nebula designated M43, and above that is…

It’s not the title of a children’s story – it’s a pair of galaxies 30 million light-years away that look like, well, a whale and a hockey stick. Officially their names are NGC 4631 and NGC 4656.

I don’t know why the press has latched onto the name “the green comet” for C/2022 E3 (ZTF) – most comets are green, and it’s too dim to see any color at all if you’re viewing it through binoculars or a telescope. But through 2 hours of total exposure time, the colors do emerge, and…

Last night marked Jupiter’s “opposition” – this is the time of year where Jupiter is at its closest point to Earth, and it’s at its biggest and brightest. By a stroke of luck, we had unusually clear skies for this event, and its moon Io was also crossing in front of Jupiter! You can see…
