When you’re Thierry Legault and you want to challenge yourself, the bar is set pretty high.

“This is a challenge I imagined some time ago,” Legault told Universe Today via email, “but I needed all the right conditions.” The challenge? Capture a transit of the International Space Station of not just the Sun — which he’s done dozens of times — but in front of a solar prominence.

Legault said the transit of the prominence, which he captured on August 21, 2015, lasted 0.8 seconds. His camera was running at 40 frames per second, and he got about 32 shots in that time.

See a video of the transit in real time, and more, below:

CAPE CANAVERAL AIR FORCE STATION, FL – Blastoff of an advanced communications satellite for the US Navy is set for early Wednesday morning, Sept. 2, using the most powerful variant of the United Launch Alliance (ULA) Atlas V rocket-following a 48 hour postponement due to terrible weather expected from Tropical Storm Erika, which pounded islands in the Caribbean causing destruction and over 20 deaths.

The threat of strong winds and heavy rains forced Florida Gov. Rick Scott to declare a state of emergency in every county in Florida last [click to continue…]

Watch the Moon Occult Aldebaran This Weekend

How about that perigee Full Moon this past weekend? Thus begins ‘Supermoon season’ for 2015, as this month’s Full Moon occurs even closer to perigee — less than an hour apart, in fact — on September 28th, with the final total lunar eclipse of the ongoing tetrad to boot. Keep an eye on Luna this week, as it crosses into the early AM sky for several key dates with destiny just prior to the start of the second and final eclipse season for 2015. [click to continue…]

What Did We Learn About Pluto?

GuideToSpace207v2

This is a video – you should watch it!

We’ve only had blurry images of Pluto up until New Horizons. So what did we learn when we got up close and personal with Pluto and its moons?

What would happen to the astronaut crews aboard NASA’s Orion deep space capsule in the event of parachute failures in the final moments before splashdown upon returning from weeks to years long forays to the Moon, Asteroids or Mars?

NASA teams are evaluating Orion’s fate under multiple scenarios in case certain of [click to continue…]

The Full Moon at 10:30 p.m. last night (Aug. 30). Even at 25° altitude, it glowed a deep, dark orange due to heavy smoke from western forest fires. Credit: Bob King

Did you see the Moon last night? I walked outside at 10:30 p.m. and was stunned to see a dark, burnt-orange Full Moon as if September’s eclipse had arrived a month early. Why? Heavy smoke from forest fires in Washington, California and Montana has now spread to cover nearly half the country in a smoky pall, soaking up starlight and muting the moonlight.

If this is what global warming has in store for us, skywatchers will soon have to take a forecast of “clear skies” with a huge grain of salt. [click to continue…]

The Dwarf Planet Orcus

Since the early 2000s, more and more objects have been discovered in the outer Solar System that resemble planets. However, until they are officially classified, the terms Kuiper Belt Object (KBO) and Trans-Neptunian Object (TNO) are commonly used. This is certainly true of Orcus, another large object that was spotted in Pluto’s neighborhood about a decade ago.

Although similar in size and orbital characteristics to Pluto, Orcus is Pluto’s opposite in many ways. For this reason, Orcus is often referred to as the “anti-Pluto”, a fact that contributed greatly to the selection of its name. Although Orcus has not yet been officially categorized as a dwarf planet by the IAU, many astronomers agree that it meets all the requirements and will be in the future.

One more thing amateur astronomers might need to worry about besides clouds, bugs, and trying to fix equipment malfunctions in the dark – and this one’s a little more serious.

NASA and the science team behind the New Horizons mission to Pluto and beyond have settled on the popular choice for the spacecraft’s next flyby: It’s 2014 MU69, an icy object a billion miles beyond Pluto that’s thought to be less than 30 miles (45 kilometers) wide.

Who doesn’t love a Full Moon? Occurring about once a month, they never wear out their welcome. Each one becomes a special event to anticipate. In the summer months, when the Moon rises through the sultry haze, atmosphere and aerosols scatter away so much blue light and green light from its disk, the Moon glows an enticing orange or red.
