Spot SpaceX’s Crew Dragon After This Weekend’s Historic Launch

How to see SpaceX’s Crew Dragon Demo Two mission in orbit.

Update: As you probably know by now, yesterday’s Crew Dragon Demo-2 launch was scrubbed due to weather violations. This is a tough one, as seas need to be relatively calm along the entire Atlantic launch track, in the event of an abort. The next launch is set for Saturday, May 30th at 3:22 AM EDT/20:33 UT, with a backup launch date of Sunday, May 31st at 3:00 AM EDT/20:00 UT. As it stands, weather prospects for both dates are currently at a 60% chance for launch violation. The weather prospects and sighting graphics in this article are updated to reflect the new launch dates, and of course, we’ll be tracking changes on Twitter as @Astroguyz.

It’s been a long time coming.

Nearly nine years after Space Shuttle Atlantis on mission STS-135 landed at the Kennedy Space Center on July 21^st, 2011, crewed missions are about to resume from U.S. soil this week, with the launch of a SpaceX Falcon 9 rocket with the historic Crew Dragon Demo 2 mission, carrying NASA astronauts Douglas Hurley and Robert Behnken to the International Space Station. And with any luck and clear skies willing, you may just be able to spy the mission chasing down the station this weekend.

Review: Galileo and the Science Deniers by Mario Livio

So, you think you know Galileo? A new book out from Simon and Schuster publishing looks at the exploits of one of the most famous astronomers there ever was: Galileo Galilei. Galileo and the Science Deniers by Dr. Mario Livio not only looks at the life and times of the famous astronomer, but busts some of the most famous myths surrounding Galileo, and looks at his greatest discoveries and tempestuous clash with the Roman Catholic Church and its aftermath. Livio also connects the science denialism of the day with comparisons to modern clashes between politics and science.

Our Review of Stellina: a ‘Smart Telescope’ for 21st Century Astronomy

Stellina may usher in a revolution in amateur astronomy.

It’s a common scene at star parties, post-Christmas. As darkness falls, someone approaches us with a new telescope, often in still unassembled. “I can’t figure this thing out,” is the inevitable refrain. “Can you show me how to use this @#$%! thing?”

Catching the Peak of the 2020 April Lyrids

Stuck at home with clear skies? We’re all in a similar situation, as the ongoing pandemic sees most of the worldwide amateur astronomy community observing from home or from their backyard. One astronomical sure-fire event coming up this week requires no special equipment, just a set of working ‘Mk-1 eyeballs’ and a clear sky: the April Lyrids.

Comet Y4 ATLAS Breaks Up…Enter Comet F8 SWAN

When it comes to comets, the only thing that is certain is the orbital path. Though the cosmos has yet to send us a really bright comet for 2020 to keep us occupied during the ongoing worldwide pandemic and lock down, it has sent us a steady stream of descent binocular comets, including C/2017 T2 PanSTARRS, C/2019 Y1 ATLAS, and C/2019 Y4 ATLAS. And though Y4 ATLAS won’t match the “Comet of the Century” media hype, another interesting binocular comet has just made its presence known over the past weekend: C/2020 F8 SWAN.

Study Finds Bizarre Exoplanet Orbits for Binary Stars

There’s an iconic scene in the original Star Wars movie where Luke Skywalker looks out over the desert landscape of Tatooine at the amazing spectacle of a double sunset. Now, a new study out of the National Radio Astronomy Observatory (NRAO) suggests that such exotic exoplanet worlds orbiting multiple stars may exist in misaligned orbits, far out of the primary orbital plane.

New Find Shows Uranus Loses Atmosphere to its Magnetic Field

You may never look at Uranus the same way again. It’s always worth combing through data from old space missions for new finds.

NASA’s researchers at the Goddard Space Flight Center recently did just that, looking at Voyager 2’s lone encounter with the planet Uranus to uncover an amazing find, as the planet seems to be losing its atmosphere to it’s lop-sided magnetic field at a high rate. The finding was published in a recent edition of Geophysical Research: Letters.

Following Comet Y1 ATLAS: the ‘Lost Comet’ of Spring

Got clear skies? If you’re like us, you’ve been putting the recent pandemic-induced exile to productive use, and got out under the nighttime sky. And though 2020 has yet to offer up a good bright ‘Comet of the Century’ to keep us entertained, there have been a steady stream of good binocular comets for northern hemisphere viewers, including C/2017 T2 PanSTARRS and C/2019 Y4 ATLAS. This week, I’d like to turn your attention to another good binocular comet that is currently at its peak: the ‘other’ comet ATLAS, C/2019 Y1 ATLAS.
