A spectacular fireball (meteor) exploded over northern Balkans today at 10:34 local time (09:34 UTC), Feb 28th. There are numerous reports of a loud sonic boom with the accompanying shockwave, strong enough to be clearly seen on the seismographs as an earthquake! Video by Tomislav Čar, posted with permission.

Call off the supernova watch. Betelgeuse is brightening again.

SUPERNOVA WATCH, CANCELLED: Call off the supernova watch.

Betelgeuse is brightening again. Researchers from Villanova University, who have been leading the study of Betelegeuse’sunprecedented decline, have confirmed in a new Astronomical Telegram that the star has reversed itself. The turnaround was actually predicted, and suggests the recent dimming was an unusually deep excursion of the star’s natural 430-day periodicity.

Here are the latest data from the American Association of Variable Star Observers (AAVSO)

After snow, sleet, and heavy wind all day, the clouds parted for a 2 hour display of spectacular pale green, blue, and purple auroras over the mountains of Reine.

Jellyfish Sprites Over Europe, 80 km high above the clouds

Posted in astronomy, Galaxy, Uncategorized with tags , , , , on June 24, 2017 by THE BOLDCORSICANFLAME AND CAPITAINE FLAMME INTREPIDE

On June 20th, a thunderstorm in Austria unleashed a spectacular display of lightning. Observers on the ground witnessed blinding flashes of crackling light. The most amazing aspect of the outburst, however, was to be found high above the clouds. 80 km high, to be exact, in the realm of the sprites

Martin Popek photographed the display from his private observatory in Nýdek, Czechia, more than 500 km away from the storm. Such distances are ideal for seeing above the tops of towering thunderclouds: diagram.

“Jellyfish sprite events like these are produced by very impulsive cloud-to-ground lightning flashes draining positive charge from the stratiform rain region in large thunderstorms,” explains lightning scientist Oscar van der Velde of the Technical University of Catalonia, Spain. Somehow, in a process that researchers only partially understand, the resulting electric fields draw jellyfish forms out of the cloudtops.

The tops of the sprites were surrounded by a saucer-like halo of red light, notes van der Velde. “The halo is evidence of intense electric fields at 80-90 km shaking up the electrons (colliding with nitrogen to produce light) for such a short time that sprite streamers cannot form. At lower altitudes the field exists longer, allowing the jellyfish sprite streamers to grow from electron avalanches.”

Although sprites have been seen for at least a century, most scientists did not believe they existed until after 1989 when sprites were photographed by cameras onboard the space shuttle.

April 1ST Comet Flyby: No kidding. Green comet 41P/Tuttle-Giacobini-Kresak is flying over Earth’s North Pole

Amateur astronomer Yasushi Aoshima sends this picture of the approaching comet from Fukushima, Japan

Green comet 41P/Tuttle-Giacobini-Kresak is flying over Earth’s North Pole this week where sky watchers can find it all night long not far from the bowl of the Big Dipper. At closest approach on April 1st it will be just 21 million km from Earth–an easy target for backyard telescopes and almost visible to the naked eye.

Amateur astronomer Yasushi Aoshima sends this picture of the approaching comet from Fukushima, Japan

“On March 22nd I caught 41P ‘eating’ M108, the Surfboard Galaxy,” says Aoshima. “The comet’s green atmosphere appeared to swallow the distant spiral galaxy as it exited Ursa Major.”

Why green? Like many comets, 41P has a verdant hue because its atmosphere contains diatomic carbon (C2)–a substance that glows green in the near vacuum of space.

Comet 41P is not only approaching Earth, but also the sun. April 12th is the date of perihelion (minimum distance from the sun). This means we are catching the comet just as solar heating is furiously searing its icy core. The green atmosphere should be well puffed up by streamers of vaporizing gas. Optimistic estimates of the comet’s brightness place it at magnitude +6, near the lower limit of naked-eye visibility.

This is not a Great Comet, but it should be a good one. The best time to observe is during the dark hours before sunrise when the green fuzzball is high in the northern sky. If you have a GOTO telescope, you can point it using an ephemeris from the Minor Planet Center. These sky maps show approximately where to look: March 31, April 1, 2.

Earth-like Planet just 39 light years away with a thick atmosphere, It could mean there’s Water

A rocky, oven-hot Earth-sized spotted orbiting a small nearby star just over a year ago is one of the best chances we have of finding alien life outside our solar system.

The planet, named GJ1132b, is around 1.2 times the size of Earth and appears to be predominantly composed of rock and iron.

Now scientists have taken the closest look yet at GJ1132b, confirming the presence of its thick atmosphere and finding hints the planet could be rich in water.

Strange Radio Bursts Seen Coming From a Galaxy Far, Far Away

The discovery of a faint radio burst in a dwarf galaxy three billion light-years away may provide scientists with a new window into the early universe, while also offering vital clues to a mystery that continues to challenge our perceptions of the cosmos.

Every day, thousands of enigmatic objects in space produce bursts of radio waves that flash for just a few milliseconds yet are capable of generating as much energy as 500 million suns.

Astronomers didn’t even know these fast radio bursts existed until a decade ago. In the years since, they’ve been scouring the cosmos, hoping that by pinpointing their locations, they might be able to figure out what—or perhaps who—is producing them.

 

Today, a team of astronomers announced that they have finally found their quarry. Relying on a global network of powerful telescopes, they managed to capture a fast radio burst that is broadcasting from a dwarf galaxy some three billion light-years away.

12/06/2016 — New Earthquake progression map — Which way does the Earth really “move”?

Posted in 2016, astronomy with tags , , on December 7, 2016 by THE BOLDCORSICANFLAME AND CAPITAINE FLAMME INTREPIDE

December 2016

This stream is showing the past 48 hours of USGS reported earthquakes + the last 50 EMSC reported earthquakes internationally.

No voice in this video unless a large earthquake strikes.

Marker height off the globe = depth into the Earth.

The feed may show double earthquakes in some locations due to both USGS + EMSC agencies reporting the events.

When an earthquake strikes, you will hear a rumble, ding, and a bell toll. The bell will toll the number of times = to the earthquake which occurs. (example : M4.0 will ring 4 times).

The most recent earthquake has a green placemark / flag on it.

Biggest supermoon in living memory set for November 14th – Nothing like it again until 2034!

Posted in 2016, astronomy with tags , , , on November 9, 2016 by THE BOLDCORSICANFLAME AND CAPITAINE FLAMME INTREPIDE

During the event, it will appear up to 14 percent bigger and 30 percent brighter than an average full moon.
The Moon is always the same size, and the distance varies by only a small amount during its orbit.

As a result, the Moon is roughly the same size in the sky every night. Even though it looks huge on the horizon, it’s identical to when it’s directly overhead.
