Current Issue: March/April 2020
Spinning a Cosmic Web
Galaxies appear to be strung together on massive filaments of dark matter with an overlay of ‘normal’ matter, which astronomers are just beginning to see.
Rulers of the Universe
An eighteenth century quest to improve the way we measure everyday objects transformed our view of the heavens.
Venus, the Evening Star, shines at its highest and brightest in March and April, while three other bright planets congregate in the early morning sky. We have details on these and many other skywatching jewels in the Sky Calendar.
Merlin answers questions about the birth of stars and navigating through the galaxy. Pose your own question for future issues.
We have details on the end of a Great Observatory, a link between whales and storms on the Sun, the case of a fading supergiant star, ancient ‘stardust’ on Earth, and much more in our news pages.
McDonald Observatory will host a dark-sky festival in April, and you can find details in our Miscellany section, along with a meditative planetarium program and more.
