Moon Pi and Mountain Shadow

Пт, Март 14, 2025 - 7:30

What phase of the Moon is 3.14 radians from the Sun? The Full Moon, of course. Even though the Moon might look full for several days, the Moon is truly at its full phase when it is Pi radians (aka 180 degrees) from the Sun in ecliptic..

The Protostars within Lynds 483

MASTER OT J095321.02+202721.2: Luminous Type II-L Supernova

Ср, Март 12, 2025 - 11:36

The optical transient MASTER OT J095321.02+202721.2, discovered in 2014, was not classified or confirmed as a supernova. We present the light curve of this object which allows us to classify it as a type II-L supernova with the absolute

У многих галактик около центров есть перемычки. Предполагается, что даже у нашей Галактики Млечный Путь есть небольшая..

APOD: 2025 March 11 Б NGC 1672: Barred Spiral Galaxy from Hubble

Вт, Март 11, 2025 - 7:30

Many spiral galaxies have bars across their centers. Even our own Milky Way Galaxy is thought to have a modest central bar. Prominently barred spiral galaxy NGC 1672, featured here, was captured in spectacular detail in an image taken..

A Probable New BY Draconis Variable ZTF J021857.72+585950.1

Пн, Март 10, 2025 - 10:43

We present our analysis of new photometric and spectroscopic data for a poorly studied star with an uncertain variability type (BY Dra or EW), ZTF J021857.72+585950.1. The observations were carried out with the 0.6-m and 2.5-m telescopes..

APOD: 2025 March 10 Б NGC 1499: The California Nebula

Пн, Март 10, 2025 - 7:30

Could Queen Calafia's mythical island exist in space? Perhaps not, but by chance the outline of this molecular space cloud echoes the outline of the state of California, USA. Our Sun has its home within the Milky Way's Orion Arm, only..

APOD: 2025 March 9 Б Cyclones at Jupiters North Pole

Вс, Март 09, 2025 - 8:30

Why are there so many cyclones around the north pole of Jupiter? The topic is still being researched. NASA's robotic Juno mission orbiting Jupiter took data in 2018 that was used to construct this stunning view of the curious cyclones at..
