You’ll find M20, the Trifid nebula, in a dark sky near the spout of the Teapot in Sagittarius. Notice the 3 westernmost (right-hand) stars of the Teapot spout, then get ready to star-hop! If you use binoculars, go about twice the spout’s distance upward until a bright hazy object glares at you in your binoculars. That’s the Lagoon nebula (Messier 8), which is visible to the unaided eye on a dark, moonless night. Once you locate the Lagoon nebula, look for the Trifid nebula as a hazy obj...| EarthSky

Venus passed between us and the sun on March 23. At that time, it moved from the evening sky to the morning sky. Now Venus is shining very brightly in the east before sunrise every morning. It’ll reach greatest brilliancy on April 27, 2025, lying not far from 2 faint-and-hard-to-see planets Saturn and Mercury. Over the coming weeks, Venus will also be climbing farther from the eastern horizon before sunrise. It’ll reach its greatest distance from the sun on May 31-June 1, 2025. Chart via ...| EarthSky

In December 2024, bright Venus continues ascending in the evening sky and will move through the constellations of Sagittarius, Capricornus and Aquarius. Venus will remain a brilliant evening star through March 2025. It’ll reach its greatest distance from the sunset in January 2025. It will shine at magnitude -4.4 by the end of month and be dazzling in the evening sky.

A hypothetical representation of a blue-colored moon. Blue-colored moons are extremely rare. They happen in a region that has experienced a major wildfire or a volcanic eruption. For example, people saw blue-colored moons after Krakatoa’s 1883 eruption and Mount St. Helens’ 1980 eruption. Will the August 19, 2024, full Blue supermoon look this color? No. It’ll be a Blue Moon in name only. Image via BlueHypercane761/ Wikimedia Commons (public domain).Next Blue Moon: August 19, 2024| EarthSky
Two spectacular star clusters glitter near the “stinger stars” – Shaula and Lesath – in the constellation Scorpius the Scorpion. Messier 6 and Messier 7 – or M6 and M7 – are open star clusters. Each cluster is a group of stars formed from the same interstellar cloud. The two clusters are visible on summer evenings in the Northern Hemisphere, or winter evenings in the Southern Hemisphere. They’re best viewed in a dark sky, and are a stunning sight through binoculars.| EarthSky

John wrote: “This is from my back window at Beaumont, Jersey, Channel Islands. This location is at 49.14 degrees, close to France, so quite a powerful aurora to have moving lights far down.” Thank you, John!What are star trails?| EarthSky
Exoplanets are worlds orbiting distant stars. Astronomer Néstor Espinoza of Space Telescope Science Institute spoke with EarthSky’s Deborah Byrd on Monday, May 20, 2024, about this diversity of worlds beyond our sun and planets. He talked about the nearby, fascinating TRAPPIST-1 system, located some 40 light-years away. He talked about Proxima Centauri b, the closest exoplanet at 4 light-years. And he touched on some current and future exoplanet missions.| EarthSky
Venus started passing behind the sun yesterday, June 3. SOHO’s LASCO C2 captured Venus about to pass behind the sun (or, in this case, behind the spacecraft imagery equipment’s sun-occulter). The occultation of Venus behind the sun – the “anti-transit” – started around 14 UTC (9 a.m. central) on June 3 as seen by SOHO’s LASCO 2 imager. Venus takes many hours to go to its deepest point behind the sun. It’ll be most deeply behind the sun today, June 4. Meanwhile, the Venus super...| EarthSky

At superior conjunction, Venus or Mercury are behind the sun from Earth. At inferior conjunction, Venus or Mercury are between the Earth and sun. At greatest elongation, Venus or Mercury are most to one side of the sun. Around greatest elongation, these inner planets, Mercury and Venus, are at their greatest distances from the sun on our sky’s dome. Chart via EarthSky.What is an elongation?| EarthSky
