Chandra Catches Pulsar Viciously Beat Massive Star B1259 - http://clapway.com/2015/07/25/chandra-catches-pulsar-viciously-beat-massive-star-b1259-567/

If you’ve never been in a street fight, and boxing is too technical to follow, then before you sprint to your nearest dojo, consider that all the punches delivered in the history of humanity are to what a pulsar travelling at a good chunk of light speed just did to a disk of matter orbiting a giant star. Bruce Lee said to kick to the moon, but Chandra just captured this pulsar just punting the equivalent of a planet into interstellar space.


CHANDRA HAS THE BEST SEAT IN THE HOUSE


Astronomers using the Chandra X-Ray Observatory orbiting the Earth witnessed the gigantic star called B1259 take this merciless beating in its home constellation Crux, also known as the Southern Cross. The punchee, B1259, is actually 30 times the mass of our Sun, and rotates at speeds so inconceivable that it actually bulges out at its sides. The puncher is a pulsar, i.e. an immensely dense mass of neutronium – the remains of an ancient star which, judging by how much is left of the pulsar, must have been even larger than its current punching bag.


I say punching bag because this mad pulsar actually forms a binary system with the star in an elliptical orbit of such high velocity that it punches right through the star’s extraneous disk every 3.5 years or so.


AFTERMATH’S HUMANITY


Astronomers observed the aftermath of this recent violence solemnly announced that the effected matter was hit with such magnificent force that what’s left of it has been expelled into interstellar space at 15 percent light speed (over 20 million miles per hour!).


Oleg Kargaltsev , Assistant Professor of Physics at George Washington University in Washington D.C. opined that “[a]fter this clump of stellar material was knocked out, the pulsar’s wind appears to have accelerated it, almost as if it had a rocket attached.”


His colleague, Jeremy Hare, added that “[t]his just shows how powerful the wind blasting off a pulsar can be…[t]he pulsar’s wind is so strong that it could ultimately eviscerate the entire disk around its companion star over time,” making what’s likely the most megalithic and apt use of the verb in the history of the English language.”


CHANDRA’S BEGINNINGS


Years before it exploded, the Columbia space shuttle installed the Chandra X-ray telescope in orbit in the year 1999. Once released, the scope boosted itself up into a particularly flashy elliptical orbit of its own, beyond Earth’s outermost charged-particle rings. This enabled Chandra to help us ogle the most heated spaces in the universe by virtue of its superlative X-ray tech.


It will be another 41 months before the next slug fest begins, so until then feel free to peruse this Astrophysical Journal at your leisure, ladies and gents.

Learning new things about #Pluto and #Charon is the new norm as of yesterday. - http://clapway.com/2015/07/15/pluto-and-charon-shows-their-unique-orbit-245/

Upon reception of new data and photographs from the New Horizons mission that flew by Pluto on Tuesday, scientists are now reporting that, unlike the earth and the moon’s orbit, Pluto and Charon have quite a divergent orbit. It’s so different, in fact, that it is the only instance of this type of orbit in the solar system.


What’s different about Pluto and Charon’s orbits?


The data from the mission revealed new information about both Pluto and Charon. It was found that Pluto is only somewhere around 8 ½ times more massive than its moon Charon. On top of this, Pluto and Charon are only 12,200 miles (19,634 km) apart. To put this in perspective, Earth is about 81 times more massive than the moon and are 238,900 miles (384,472 km) apart. Because the differences in mass are so minute and because they are so close, Charon doesn’t actually orbit around Pluto.


In reality, Pluto and Charon have what is known as a binary system, and this is the only orbit of its kind in our solar system. What this means is that the small difference of masses and the close proximity causes both cosmic bodies to pull on each other, creating a gravitational point between the two that Pluto and Charon both orbit.


How is this orbit possible?


Scientists first reactions were that Charon was once a piece of Pluto that was broken off due to a cataclysmic collision with another planetoid. This is very similar to how our moon was formed. However, further investigation shows that Pluto and Charon are almost too different for that theory to be viable.


Pluto is very rocky and has a very thick atmosphere while Charon is made of about as much ice as it is rock and has no atmosphere at all. There are nitrogen, methane, and carbon monoxide ices on Pluto, but Charon mainly has water and ammonia ice. As of now, it is clear that the two bodies have been together for billions of years, yet they are so incredibly different.


What about Pluto’s other moons?


Pluto has four other, smaller moons besides Charon: Hydra, Nix, Kerberos, and Styx. Like Pluto and Charon, they also orbit the gravitational point the two larger bodies create. Because they orbit two different cosmic bodies, the sun could rise in the east and set in the west on one day, then rise in the west and set in the south on another. Since the four smaller moons orbit the gravitational pull at a farther distance, it is safe to say that the binary system of both Pluto and Charon have four moons.
