A star about 3,000 light years away is normally very dim--requiring a telescope and a dark sky to see. About 80 years ago, it flared up to easy naked eye visibility. Some astronomers think it might be about to flare up again.Also, the moon is
All the planets will soon by on the same side of the sun. When something like that happened in 1982, some people carried on like the world would come to an end. Most scientists recognized the so-called alignment as an important opportunity.
Mars and Neptune will appear very close. To see this super close conjunction, you will need to be in a place where it's still dark when they're up. And you'll need magnification. How much? Not much. But you need something else too.
Earth is passing through the dust stream that produces the April Lyrid meteor shower this week. There are sometimes bright fireballs. The full moon is interfering though.
What an exciting week that just ended with a total solar eclipse. Red prominences showed in the corona. Why are they that color? And what did scientists learn about the sun by analyzing the corona's spectum?
Several planets are lined up in the morning. The moon is with them at first. One more admonition to protect your eyes during the solar eclipse. Several planets appear close to the sun during the eclipse. Then the moon passes Mercury and Jupiter
Mercury's leaving the evening sky. Jupiter is heading toward Uranus. Three planets are leaving the morning sky, but there's time for the moon to meet up with them. And here's some more advice on how to experience the total solar eclipse.
Legends abound about seven stars and why only six of them are visible. We review what the ancient Greeks said about the Pleiades and which Pleiad is missing.As Comet Halley is at the halfway point between appearances, another comet with an orb
Evening planet viewing isn't so bad right now. It's getting hard to see the morning planets. There will be a penumbral lunar eclipse next week.
There are a lot of things to think about if you will travel to see the total solar eclipse next month. Do you need a place to stay? Where will you eat while you're there? How will you keep everyone in your party occupied during the trip?Maybe
An asteroid is at opposition this week. It's one of the asteroids discovered by the "celestial police" who looked over areas of the sky for objects between Mars and Jupiter. And there's a reason they expected to find something there. But maybe
Jupiter still rules the evening. Venus and Mars are leaving the morning sky. The moon will soon pass in front of Antares. And part of a famous but long lost star catalog has been found.
An evening planet is heading into the sunset. Three morning planets are heading into the sunrise. And there will soon be a conjunction of two planets with each other and with the sun!
The moon will pass in front of Elnath for viewers in part of Australia and Indonesia next week. Scientists can learn a lot about a star that's hidden that way. And several planets are on their way out of the night sky.
Southern hemisphere observers can take a double challenge--try to see some meteors and then figure out which of two overlapping showers they came from. It's not easy. Both radiate from the same constellation and neither shower produces a lot of
You may have noticed that the sun rarely crosses the meridian when the clock says it's 12pm. High noon is about as late as it gets this time of year.Some planets are leaving the morning sky. Some are leaving the evening sky.
Saturn's disappearing from the evening sky. The moon's approaching full phase and northern lunistice. It's Venus's turn to apparently pass by a very distant star. And the morning planetary action lately deserves applause, because it's associate
The moon goes through first quarter. Orion and Gemini are becoming prominent. Three planets are in the morning sky. Mercury is about to (appear to) pass by a star nearly 30,000 light years away.
As three planets move in the morning sky this week, the moon passes them by.
In 2024, the moon will pass in front of bright stars several times, there'll be a total solar eclipse, increasing solar activity could mean more aurorae, and the moon will reach its farthest north and south since 2006. In just the next few week
There's planet watching in the evening and morning. Venus passes through Libra. And there's a star, not very far away as cosmic distances go, that might be almost as old as the universe. You can actually see it with binoculars.
Linda Salzman Sagan, who designed the plaque on the Pioneer 10 and 11 probes, died last month. Her art sure got people talking.The asteroid Vesta is at opposition this week.
It's been 38 years since the solar system's most famous comet was closest to the sun. It'll be 38 more before it's back. Comet Halley was farthest from the sun this month.
Mercury's at greatest elongation this week. Saturn's still up in the evening. Jupiter's about to turn around. Venus and the moon pair with a dragon star. Mars is still missing.English speakers say the moon is at first quarter or last quarter.
It's been a half-century since Pioneer 10 went by Jupiter. And it's been 20 years since anyone last heard from the probe. Whatever's next for it will probably be in almost 40,000 years.
