The evening Moon climbs toward the Arch of Spring, then through it. Orion's Belt levels, the Leaps of the Gazelle cross the zenith, and Saturn and Mars conjoin near brilliant Venus in early dawn.
Floofy Objects and Other Tales of Astronomical Impossibility
Astronomers aren't holding back this year, with brand-new submissions to this year's highly prestigious (and fictitious) Acta Prima Aprilia.
Comets to View in 2022
Like comets? We've got 11 frozen fuzzies to share with you in the coming months, including a couple that could become fine binocular objects.
Meet Earendel, the Most Distant Star Astronomers Have Observed
The Hubble Space Telescope has revealed a single star whose light has traveled for 12.9 billion years to Earth — the most distant star known.
Where Did the Ice Giants Form?
Conventional planet formation scenarios have Neptune and Uranus forming closer to the Sun. But a new study shows that the ice giant planets could have formed right where they are now.
“Lucky” Images Reveal Dusty Debris Around a Star 330 Light-years Away
The transit of a large cloud of protoplanetary rubble across the face of a young star gave the Spitzer Space Telescope our best view yet of planetary evolution in action.
New Image Reveals Possible Origins of “Odd Radio Circles”
This faint ring of radio emission might signal a momentous event in galactic evolution. Then again, it might be something else entirely.
This Week's Sky at a Glance, March 25 – April 2
What constellation trots behind Sirius and Canis Major across the southern sky? Puppis, not a puppy but the poop deck of Argo Navis. In this dark of the Moon, try for the Clown-Face Nebula high in Gemini. And the three dawn planets dance through two more isosceles triangles.
Hundreds of Thousands of Stars Reveal the Milky Way’s “Teenage” Years
A census of hundreds of thousands of subgiant stars in our galaxy provides a window into the Milky Way's early history.
Meet Procyon, Orion’s Littler Dog
Meet Procyon, the brightest of the few stars in Canis Minor, the Lesser Dog. On its way to becoming a giant, this star is part of the Winter Triangle and Wniter Hexagon asterisms.
The History of Venus in Air, Rock, and Water
Forty years ago, NASA's Magellan mission “closed the book” on Venus. Now, a new generation of astronomers think the planet next door deserves a second chance.
Is “Slow Science” the Answer to Astronomy's Carbon Footprint?
The first quantitative assessment of professional telescopes’ carbon footprint finds that these facilities contribute more emissions than all other astronomy research activities combined.
This Week's Sky at a Glance, March 18 – 26
Sirius sparkles on the corner of the Meat Cleaver, two open clusters hide under the Cleaver's handle, Orion's Belt levels out for the turning of spring, and Venus, Mars and Saturn slow-dance at dawn.
Pulsar Shoots 7-light-year-long Phaser Blast
Nature proves truth is still stranger than fiction: A pulsar has shot energetic particles in a thin, straight line that extends for light-years into space. The discovery might explain how antimatter makes its way to Earth.
Will Saturn Sprout Spots this Observing Season?
As Saturn returns to the morning sky, will this otherwise serene-looking planet experience another bout of severe weather? Keep your eyes peeled for white spots!
