Astronomy Picture Of the Day (APOD)
APOD: 2023 June 18 Б Saturns Northern Hexagon
18.06.2023
Why would clouds form a hexagon on Saturn? Nobody is sure. Originally discovered during the Voyager flybys of Saturn in the 1980s, nobody has ever seen anything like it anywhere else in the Solar System.
Planet Earth at Night II
17.06.2023
Recorded during 2017, timelapse sequences from the International Space Station are compiled in this serene video of planet Earth at Night. Fans of low Earth orbit can start by enjoying the view as green and red aurora borealis slather up the sky.
Sunset to Sunrise over the Baltic Sea
16.06.2023
This serene view from the coast of Sweden looks across the Baltic sea and compresses time, presenting the passage of one night in a single photograph. From sunset to sunrise, moonlight illuminates the creative sea and skyscape. Fleeting clouds, fixed stars, and flowing northern lights leave their traces in planet Earth's sky.
M15: Dense Globular Star Cluster
15.06.2023
Messier 15 is an immense swarm of over 100,000 stars. A 13 billion year old relic of the early formative years of our galaxy it's one of about 170 globular star clusters that still roam the halo of the Milky Way.
APOD: 2023 June 14 Б The Shark Nebula
14.06.2023
There is no sea on Earth large enough to contain the Shark nebula. This predator apparition poses us no danger as it is composed only of interstellar gas and dust. Dark dust like that featured here is somewhat like cigarette smoke and created in the cool atmospheres of giant stars.
APOD: 2023 June 13 Б Moons Across Jupiter
13.06.2023
Jupiter's moons circle Jupiter. The featured video depicts Europa and Io, two of Jupiter's largest moons, crossing in front of the grand planet's Great Red Spot, the largest known storm system in our Solar System.
APOD: 2023 June 12 Б The Largest Satellites of Earth
12.06.2023
WhatБs that near the Moon? ItБs the International Space Station (ISS). Although the ISS may appear to be physically near the Moon, it is not Б it is physically near the Earth.
APOD: 2023 June 11 Б The Sun and Its Missing Colors
11.06.2023
Here are all the visible colors of the Sun, produced by passing the Sun's light through a prism-like device. The spectrum was created at the McMath-Pierce Solar Observatory and shows, first off, that although our white-appearing Sun emits light of nearly every color, it appears brightest in yellow-green light.
Mars and the Beehive
10.06.2023
This month, bright Mars and brilliant Venus are the prominent celestial beacons in planet Earth's western skies after sunset. Wandering through the constellation Cancer the Crab, the Red Planet was captured here on the evening of June 3 near the stars of open cluster Messier 44.
Pandora s Cluster of Galaxies
9.06.2023
This deep field mosaicked image presents a stunning view of galaxy cluster Abell 2744 from the James Webb Space Telescope's NIRCam. Also dubbed Pandora's Cluster, Abell 2744 itself appears to be a ponderous merger of three different massive galaxy clusters some 3.5 billion light-years away toward the constellation Sculptor.
