Space and astronomy news
A citizen science initiative called Globe at Night has some sobering news for humanity. Our artificial light is drowning out the night sky for more and more people. And it’s happening more rapidly than thought.

With the rapid expansion of commercial space, there is a growing number of satellites in orbit around our planet. Most of these are in low-Earth orbit, which is becoming increasingly crowded. This has led some to be concerned about a catastrophic rise of space debris, as well as a growing frustration by astronomers due to the number of satellite sky trails.

In this series we are exploring the weird and wonderful world of astronomy jargon! You’ll surely measure the awesomeness of today’s topic: absolute magnitude!

The night sky is a part of humanity’s natural heritage. Gazing up at the heavens is a unifying act, performed by almost every human that’s ever lived. Haven’t you looked up at the night sky and felt it ignite your sense of wonder?
But you can’t see much night sky in a modern city. And the majority of humans live in cities now. How can we regain our heritage? Can quiet contemplation make a comeback?

Light pollution is the arch nemesis of astronomy, spoiling both the enjoyment of the night sky and the professional study of our universe. For years we’ve assumed that streetlights are the main culprit behind light pollution, but a recent study has shown that streetlights contribute no more than 20% of all the pollution, and if we want to solve this vexing astronomical problem, we have to think harder.

You might’ve heard the news. We wrote a book this past year: The Universe Today’s Ultimate Guide to Observing the Cosmos: Everything You Need to Know to Become an Amateur Astronomer. Judging from reader feedback thus far, one of the most popular parts of the book is Chapter 10, where we list the top astronomical events by year for the coming six years. True story… we picked six (2019 to 2024) to stretch out the list to touch on the April 8th, 2024 total solar eclipse. Continue reading “Top Astronomy Events For 2019”
When it comes to meteor showers, the calendar year always seems to save the best for last. We’re referring to the Geminid meteor shower, one of the sure fire bets for dependable meteor showers. In fact, in recent years, the Geminids have been upstaging that other yearly favorite: the August Perseids. If the Geminids did not occur in the chilly (for the northern hemisphere) month of December, they’d most likely get a better rap. Continue reading “Get Ready for the 2018 Geminid Meteors”
It’s a never-ending quest for observers, lovers of the night sky and astrophotographers. Where to go to get away from encroaching light pollution, and find truly dark skies?
Most of us think of distant sites such as Death Valley, the Kalahari Desert or the Canary Islands when it comes to dark skies. And while it’s true that many observers are now traveling farther and farther away from home in search of truly dark skies, that trip need not be as far as you think.
We had the opportunity to visit one such often overlooked dark sky gem: the state of Nebraska. From fossils to aeronautics and astronomy, there’s lots of science to explore in the Cornhusker State. Though the state has a rich science heritage, and an active amatuer astronomy community, Nebraska is an often overlooked dark sky haven. But science tourism is also becoming increasingly popular, and Nebraska has lots to offer.

A relatively obscure meteor shower may put on a surprise performance in early December 2018. Chances are, you’ve never heard of the Andromedids, though it’s worth keeping an eye out for these swift-moving meteors over the next week. Continue reading “A 2018 Outburst From the December Andromedids?”
UPDATE – SpaceX has now set a firm date and time for the Spaceflight SSO-A launch from Vandenberg Air Force Base for Monday, December 3nd at 18:31 Universal Time (UT).
A unique smallsat mission promises to be the latest satellite “brighter than a Full Moon!” in the night sky… or not.
The Mission: We’re talking about Orbital Reflector, conceived by Trevor Paglen and fielded by the Nevada Museum of Arts. Dubbed as the “first art exhibit in space,” the $1.3 million dollar project seeks to put a smallsat payload with a deployable reflector in low Earth orbit.
