This meteor shower is best observed if you are patient and watch from after midnight until just before dawn, from a dark location far from city lights. The radiant of this meteor shower is in the constellation Boötes, but meteors can appear anywhere in the sky.
Jan 10, 2025
Venus reaches its greatest eastern elongation of 47.2 degrees from the Sun. This is the best time to observe Venus, when it is at its highest point above the horizon in the evening. Look for a bright, prominent dot in the western sky just after sunset – that is Venus.
Jan 13, 2025
The Moon will be in opposition, with its surface reflecting the maximum amount of sunlight toward Earth. This phase occurs at 22:26 UTC. This Full Moon is called the Wolf Moon, as wolves were often heard howling during the deep winter nights of January.
Jan 16, 2025
At opposition, Mars, the Earth and the Sun are almost aligned. The planet’s surface reflects the most sunlight towards Earth, so Mars becomes brighter than at any other time of the year and is visible all night long. This is the best time to observe and photograph Mars. Through a telescope, you can see the dark surface features of Mars.
Mar 8, 2025
Mercury reaches its greatest eastern elongation of 18.2 degrees from the Sun. This is a rare chance to see the planet in a dark sky, when it is at its highest point above the western horizon. Look to the west just after sunset and you may spot a small but noticeable bright dot – that is Mercury.
Mar 13 – 14, 2025
A lunar eclipse occurs when the Earth is positioned between the Sun and the Moon, causing the Earth’s shadow to cover the Moon. This phenomenon only happens during the Full Moon phase. A total lunar eclipse occurs when the entire Moon enters the Earth’s umbral shadow. The Moon does not disappear but instead turns a coppery red color due to sunlight being refracted through the Earth’s atmosphere. This lunar eclipse will be visible in Europe, Much of Asia, Much of Australia, Much of Africa, North America, South America, Pacific, Atlantic, Arctic, Antarctica.
Mar 14, 2025
The Moon will be in opposition, with its surface reflecting the maximum amount of sunlight toward Earth. This phase occurs at 06:54 UTC. This Full Moon is called the Worm Moon, because the ground begins to thaw and earthworms emerge, signaling the arrival of spring.
Apr 13, 2025
The Moon will be in opposition, with its surface reflecting the maximum amount of sunlight toward Earth. This phase occurs at 00:22 UTC. This Full Moon is called the Pink Moon, named after pink wildflowers such as phlox that bloom in early spring — not because the Moon itself appears pink. This Full Moon is a micromoon because it occurs when the Moon is at its farthest point from Earth in its elliptical orbit, making it appear slightly smaller and dimmer than usual.
Apr 21, 2025
Mercury reaches its greatest western elongation of 27.4 degrees from the Sun. This is the best time to see the planet in the early morning sky, when it is at its highest point above the eastern horizon.
