The Strangest Eclipse Fact Of All: The Moon’s Shadow Isn’t A Circle

“These imperfections along the edge of the lunar limb don’t just reflect peaks and valleys on the Moon’s surface, but result in sharp edges and corners appearing on the Moon’s shadow as well. Thanks to incredibly accurate mapping of elevation of the entire lunar surface by NASA’s Lunar Reconnaissance Orbiter, we know exactly what the profile of the Moon looks like. Combine that information with the Earth-Moon-Sun orbit, and we can derive what irregularities will be present during the August 21st, 2017 (or any) solar eclipse, when the Moon’s shadow passes across Earth’s surface.”

The Moon is spherical, and so its shadow should be a circle by simple geometry, right? Only, if we view it when it strikes Earth, it’s not even close to a circle. It’s stretched into an ellipse, and further complicated by irregular, sharp edges and corners. Why would it appear that way? As it turns out, three factors combine to get us there. The first is the fact that Earth is a sphere, not a disk, so any shadow falling on it gets stretched. The second is that the Moon’s sharp peaks, valleys and craters mean that its shadow gets irregularly distorted in a way that changes as its orbit continues. And the third is that Earth isn’t smooth, but exhibits significant changes in elevation and terrain.

Add them all up, and you’ve got the incredibly bizarre and ever-changing shape of the Moon’s shadow. Come see what the eclipse of August 21, 2017 will hold!

Black Hole Caught Devouring Star For An Entire Decade

“Normally lasting weeks or months, a new record has just been set for TDEs. XJ1500+0154, 1.8 billion light years away, is the largest, longest-lasting one ever seen. First detected in July of 2005, the X-rays from this distant source brightened by a factor of 100 over 3 years. They remain bright even today. Although dozens of TDEs have been observed since the 1990s, none have lasted this long. It may be caused by the most massive star ever observed creating a TDE.”

When any object passes too close to the event horizon of a black hole, the tidal forces acting on it can become so strong that they’ll tear the entire object apart in a spaghettification disaster. While most of the matter will get ejected from the encounter, a significant fraction can be accreted, absorbed and used to fuel the black hole’s growth. These tidal disruption events have been seen numerous times since the launch of our X-ray observatories, and are now known to come in a wide variety of magnitudes, at a variety of distances and to last a variable amount of time. So when you see the largest, longest-lasting one ever, you sit up and take notice! That’s exactly what’s happened with XJ1500+154, which is now in its second decade of X-ray signals.

Come get the full story on this amazing object, and learn how it might solve the puzzle of supermassive black hole growth on today’s Mostly Mute Monday!

In the next 3 weeks, Canada will make a decision that could save the bees for good

We won't see another opportunity like this again. Let's seize it.

um guys?

canada is currently considering banning imidacloprid, which is apparently “one of the most widely used bee-killing pesticides in the world”. this seems pretty huge, so if you’ve got two seconds, add your name to the list! as of posting this link, they need just over 8,000 more signatures by february 21!

The Science Has Spoken: Pluto Will Never Be A Planet Again

“What’s perhaps most remarkable is that we can make a simple, mathematical relationship between a world’s mass and its orbital distance that can be scaled and applied to any star. If you’re above these lines, you’re a planet; if you’re below it, you’re not. Note that even the most massive dwarf planets would have to be closer to the Sun than Mercury is to reach planetary status. Note by how fantastically much each of our eight planets meets these criteria… and by how much all others miss it. And note that if you replaced the Earth with the Moon, it would barely make it as a planet.”

It was a harsh lesson in astronomy for all of us in 2006, when the International Astronomical Union released their official definition of a planet. While the innermost eight planets made the cut, Pluto did not. But given the discovery of large numbers of worlds in the Kuiper belt and beyond our Solar System, it became clear that we needed something even more than what the IAU gave us. We needed a way to look at any orbiting worlds around any star and determine whether they met a set of objective criteria for reaching planetary status. Recently, Alan Stern spoke up and introduced a geophysical definition of a planet, which would admit more than 100 members in our Solar System alone. But how does this stand up to what astronomers need to know?

As it turns out, not very well. But the IAU definition needs improving, too, and modern science is more than up to the challenge. See who does and doesn’t make the cut into true planetary status, and whether Planet Nine – if real – will make it, too!
