Seven New Multiperiodic delta Scuti stars in Cygnus

Ср, Май 15, 2024 - 11:17

In a small field in Cygnus, I discovered seven new DSCTC stars that demonstrate multiperiodic pulsations from V-band CCD observations. For each of these stars, from two to four reliable pulsation frequencies could be derived. The..

APOD: 2024 May 15 Б AR 3664 at the Suns Edge

Ср, Май 15, 2024 - 7:30

What did the monster active region that created the recent auroras look like when at the Sun's edge? There, AR 3664 better showed its 3D structure. Pictured, a large multi-pronged solar prominence...

The 37 Cluster

Вт, Май 14, 2024 - 12:30

For the mostly harmless denizens of planet Earth, the brighter stars of open cluster NGC 2169 seem to form a cosmic 37. Did you expect 42? From our perspective, the improbable numerical asterism appears solely by chance. It lies at..

APOD: 2024 May 13 Б AR 3664 on a Setting Sun

Вт, Май 14, 2024 - 12:30

It was larger than the Earth. It was so big you could actually see it on the Sun's surface without magnification. It contained powerful and tangled magnetic fields as well as numerous dark sunspots.

APOD: 2024 May 12 Б Red Aurora over Poland

Вт, Май 14, 2024 - 12:30

Northern lights don't usually reach this far south. Magnetic chaos in the Sun's huge Active Region 3664, however, produced a surface explosion that sent a burst of electrons, protons, and more massive, charged nuclei into the Solar..

APOD: 2024 May 11 Б AR 3664: Giant Sunspot Group

Сб, Май 11, 2024 - 8:30

Right now, one of the largest sunspot groups in recent history is crossing the Sun. Active Region 3664 is not only big -- it's violent, throwing off clouds of particles into the Solar System. Some of these CMEs are already impacting..

Simulation: Two Black Holes Merge

Пт, Май 10, 2024 - 8:30

Relax and watch two black holes merge. Inspired by the first direct detection of gravitational waves in 2015, this simulation plays in slow motion but would take about one third of a second if run in real time. Set on a cosmic stage, the..
