This month's astronomy podcast guides you around the nighttime sky during April, giving you easy-to-follow help for finding bright planets and key stars after the Sun goes down.
A new analysis of more than 800 telescopic observations suggests that our first known interstellar visitor could have the shape of a cigar or a fat disk.
A controversial 1950 book by Immanuel Velikovsky declared that our neighbor world was spawned by Jupiter 3,500 years ago and nearly struck Earth — twice.
With winter's chill fading away, this is a great time to gaze up into the stars — and to be ready for an evening appearance by fleet-footed Mercury. This month's astronomy podcast guides you around the nighttime sky.
February's astronomy podcast offers you a trio of bright planets to spot before dawn and a plethora of bright stars to check out each evening.
Get ready for a celestial event — a total lunar eclipse during the month's second full Moon and near lunar perigee — that hasn't happened in 35 years!
Thick sheets of water ice, some barely buried beneath the surface and likely more than 100 meters thick, have been spotted on several Martian cliff faces.
January's astronomy podcast describes how to spot Mercury, Mars, Jupiter, and Saturn in the predawn sky during January — plus you'll learn about a "trifecta" full Moon at month's end.
Two total lunar eclipses occur this year, the first since late 2015, in January and July. Meanwhile, three solar eclipses take place in 2018 — all of them only partial cover-ups.
More than a dozen times each year, we experience a pulse of "shooting stars" from an annual meteor shower. Sky & Telescope predicts that the two best meteor showers in 2018 will be the Perseids in mid-August and the Geminids in mid-December.
Astronomers' recent observations of our first-known interstellar visitor reveal that it is very strange indeed.
For a young woman who stared too long on August 21st, the partially eclipsed Sun left a lasting impression — on her retinas.
A new analysis reveals that the gigantic impact that led to the Moon's formation might have also switched on Earth's magnetic field.
As you'll hear in December's astronomy podcast, early risers are treated with views of Jupiter (obvious), Mars (not as easy), and Mercury (timing is everything!).
The U.S. National Science Foundation will continue to fund the iconic radio dish, though at a much-reduced level, as it seeks partners to share in the facility's operation.
Rapid-response observations by major observatories shows that the first-known interstellar visitor is 10 times longer than it is wide.
The arrival of an object from beyond the solar system caught astronomers by surprise — but that doesn't mean that they were unprepared to study it.
Observations from NASA's MAVEN spacecraft reveal that the solar wind causes unexpected interactions with the Red Planet's weak magnetism.
As you'll hear in this month's astronomy podcast, Venus and Jupiter are putting on quite a show low in the east before dawn.
Telescopes only picked it up a week ago, but it's likely been traveling through interstellar space for millions of years.
A professional observatory in Greece has begun recording flashes created when bits of interplanetary debris strike the Moon.
You'd think scientists would have Saturn all figured out after watching it up close for 13 years. They don't.
When the distant dwarf planet Haumea briefly slipped in front of a star last January, astronomers found more than they expected.
After protests and a judge's ruling brought the colossal Thirty Meter Telescope project to a halt, a state panel has cleared the way for its construction atop Mauna Kea to proceed.
October's astronomy podcast helps you track down Saturn after sunset and offers a peek at what's in view before dawn.
