Astronomy Picture Of the Day (APOD)
Eclipse Street, Hong Kong
25.06.2020
On June 21 an annular solar eclipse came soon after the solstice and our fair planet's northernmost sunset for 2020. At maximum eclipse, the New Moon in silhouette created a ring of fire visible along a narrow path at most 85 kilometers wide.
Inverted City Beneath Clouds
24.06.2020
How could that city be upside-down? The city, Chicago, was actually perfectly right-side up. The long shadows it projected onto nearby Lake Michigan near sunset, however, when seen in reflection, made the buildings appear inverted.
The X Ray Sky from eROSITA
23.06.2020
What if you could see X-rays? The night sky would seem a strange and unfamiliar place. X-rays are about 1,000 times more energetic than visible light photons and are produced by violent explosions and high temperature astronomical environments.
Moon Occults Venus
21.06.2020
It may look like Earthrise, but it's actually Venus-set. Just after sunrise two days ago, both the Moon and Venus also rose. But then the Moon overtook Venus. In the featured image sequence centered on the Moon, Venus is shown increasingly angularly close to the Moon.
Northern Summer on Titan
20.06.2020
Today's solstice brings summer to planet Earth's northern hemisphere. But the northern summer solstice arrived for ringed planet Saturn over three years ago on May 24, 2017. Orbiting the gas giant, Saturn's moon Titan experiences the Saturnian seasons.
The Veins of Heaven
19.06.2020
Transfusing sunlight through a darkened sky, this beautiful display of noctilucent clouds was captured earlier this week, reflected in calm waters from Nykobing Mors, Denmark. From the edge of space, about 80 kilometers above...
The Tadpoles of IC 410
18.06.2020
This telescopic close-up shows off the central regions of otherwise faint emission nebula IC 410, captured under backyard suburban skies with narrowband filters. It also features two remarkable inhabitants of the cosmic pond of gas and dust. Below and right of center are the tadpoles of IC 410.
Magnetic Streamlines of the Milky Way
17.06.2020
What role do magnetic fields play in interstellar physics? Analyses of observations by ESA's Planck satellite of emission by small magnetically-aligned dust grains reveal previously unknown magnetic field structures in our Milky Way Galaxy -- as shown by the curvy lines in the featured full-sky image.
APOD is 25 Years Old Today
16.06.2020
Welcome to the quadranscentennial year of the Astronomy Picture of the Day. Perhaps a source of consistency for some, APOD is still here. To help celebrate APOD's Silver Anniversary, some of APOD's TVAoTaSMD have recorded a birthday greeting and thanks to APOD's readership in today's featured video.
A Ring of Fire Sunrise Solar Eclipse
15.06.2020
What's rising above the horizon behind those clouds? It's the Sun. Most sunrises don't look like this, though, because most sunrises don't include the Moon. In the early morning of 2013 May 10, however, from Western Australia, the Moon was between the Earth and the rising Sun.
