Why can’t we see the far side of the moon?
Some people see a face in the moon; others see a rabbit or a toad. But regardless of what you see on the lunar surface, we all view the same side of our natural satellite. So why don’t we ever see the far side of the moon? From Earth, it appears as if the moon…

50 of the greatest, most famous astronomers of all time
Who are the greatest and most famous astronomers of all time? The history of astronomy is the story of how humanity has uncovered the secrets of the cosmos, from early astronomers defining the mechanics of the Solar System and how the night sky changes over time, to astrophysicists studying the chemistry of stars, the expansion…

A Severe Solar Storm Is Hitting the Earth, and Auroras May Be Visible
Officials warned of potential blackouts or interference with navigation and communication systems this weekend, as well as auroras as far south as Northern California or Alabama. NASA’s Solar Dynamics Observatory captured these images of the solar flares, as seen in the bright flashes in the upper right, on May 5 and May 6. The image…

Blinded by the light: How bad are satellite megaconstellations for astronomy?
Over the past few years, our planet has become increasingly encircled by Starlink, OneWeb and other “megaconstellation” satellites. Yes, the emergence of those megaconstellations offers great benefits for humanity. But in a wait-a-minute pause, there are also substantial costs, including a growing imposition on astronomy. That’s the view of David Koplow, the Scott K. Ginsburg…

Observing the invisible. How astronomers use the electromagnetic spectrum to explore the Universe
Electromagnetic waves are a form of energy that have both an electric and magnetic component. They’re different from mechanical waves since they’re one of the only things that can propagate long distances through the vacuum of space.

Black hole collision ‘alerts’ could notify astronomers within 30 seconds of detection
In 2015, the iconic Laser Interferometer Gravitational-Wave Observatory (LIGO) made the first-ever tangible detection of gravitational waves. The waves were the result of two black holes colliding far away in the universe; since then, a wealth of such signals from merging black holes, neutron stars and even a couple of mixed mergers between the two…
