Brightest Supernova Ever Discovered Amazes And Confounds

Last June, the All-Sky Automated Survey for Supernovae (ASAS-SN — think “assassin”) discovered a faint flicker of starlight in an unremarkable galaxy in the far southern constellation of Indus the Indian. Hundreds of supernovae are discovered every year, but this one was different. Once it was determined the exploding star lay 2.8 billion light years from…

Hubble Uses Gravity Axe To Cleave One Supernova Into 4

Gravity gathers together and hews apart. The powerful gravity of a galaxy embedded in a massive cluster of galaxies called MACS J1149.6+2223 has split the light of distant supernova into four separate images, a phenomenon predicted by Einstein called gravitational lensing. Although astronomers have discovered dozens of multiply imaged galaxies, they’ve never seen a lensed supernova explosion until last November.…

Doomed Stellar Relationship To End In Supernova Catastrophe

I’ve had a few relationships explode but none like what’s going to happen to this couple in 700 million years. A team of astronomers, led by Miguel Santander-Garciá (Observatorio Astronómico Nacional, Alcalá de Henares, Spain), has discovered a close pair of white dwarf stars in the core of the planetary nebula Henize 2-428 in constellation Aquila…

Mercurial Delights / Supernova In Spiral Galaxy M61 / Jupiter Spots

Scattered thin clouds took nothing away from this morning’s otherwise clear sky. With the Moon waxing from quarter to gibbous phase, the slab of darkness between moonset and dawn gets sliced thinner every day. Starting November 4th the Moon will light the sky all night and not give back the darkness till next weekend. I took…

Moon, Mars, Saturn And Antares Gather At Dusk Tonight

Don’t miss tonight’s sweet gathering of crescent moon and evening planets. Just look to the southwest in late twilight to spot the trio. Both Saturn and Mars happen to be exactly the same brightness, shining equally at magnitude 0.8, but each with a distinctly different hue. Can you see the contrast between rusty red Mars…
