The featured image shows meteors from the usual docile
Tau Herculids meteor shower. The image records 19 images from the shower, with 3 other meteors also captured. In the foreground are
two telescopes from Kitt Peak: the 2.3-meter Bok telescope and the
4-meter Mayall telescope.
Please see the explanation for more detailed information.

Tau Herculids Meteors over Kitt Peak Telescopes

It was a night to remember, but it wasn't the storm of the century. The peak of the Tau Herculids meteor shower was last night. The Earth might be passing through a dense stream of comet debris, which could cause a storm of bright meteors to streak out from the constellation of Hercules. A decent meteor shower could be called after what actually happened. The image was taken at Kitt Peak National Observatory in Arizona on May 30. There were 19 Tau Herculids meteors captured, along with 4 unrelated ones. Can you find them? The Mayall Telescope is just behind the 2.3-meter Telescope in the foreground. The next active night forecast is for 2049, and the annual Tau Herculids are expected to return to their normal low rate next year.

Lunar Occultation of Venus
Image Credit & Copyright: Quentin Gineys

Explanation: On May 27 Venus rose as the morning star, near the waning crescent Moon in a predawn sky already full of planets. It was close on the sky to the Moon's crescent and a conjunction of the second an third brightest celestial beacons were enjoyed by skygazers around the world. But seen from locations along a track through southeast Asia and the Indian Ocean the Moon actually passed in front of Venus in a lunar occultation. In this animated gif the 75 percent illuminated disk of Venus approaches and just begins to disappear behind the sunlit southwestern lunar limb. The telescopic frames used to construct it were captured from Reunion Island in the Indian Ocean around 4:50am local time, with the Moon and Venus very close to the eastern horizon. At the time Venus was over 180 million kilometers from Reunion Island, compared to a lunar distance of a mere 400 thousand kilometers or so. About 50 minutes later Venus emerged from behind the Moon.
