Brand new exoplanet discovered on a BBC program about hunting for exoplanets

iheartchaos:

Earlier this week, the BBC ran the show Stargazing Live for three consecutive nights, asking viewers to examine the live telescope observations around the world and look for anything that might be an exoplanet. And after hundreds of thousands of responses, it looks like someone discovered a new exoplanet because of the show.

Astronomers report that they have taken the measure of the biggest, baddest black holes yet found in the universe, abyssal yawns 10 times the size of our solar system into which billions of Suns have vanished like a guilty thought.

One of these monsters, which weighs as much as 21 billion Suns, is in an egg-shaped swirl of stars known as NGC 4889, the brightest galaxy in a sprawling cloud of thousands of galaxies about 336 million light-years away in the Coma constellation.

The other black hole, a graveyard for the equivalent of 9.7 billion Suns, more or less, lurks in the center of NGC 3842, a galaxy that anchors another cluster known as Abell 1367, 331 million light-years away in Leo.

“These are the most massive reliably-measured black holes ever,” said Nicholas J. McConnell, a graduate student at the University of California, Berkeley, in an e-mail, referring to the new observations.

These results are more than just cool and record-setting. Observations with the Hubble Space Telescope over the years have shown that such monster black holes seem to inhabit the centers of all galaxies — the bigger the galaxy, the bigger the black hole. Researchers said that the new work could shed light on the role these black holes play in the formation and evolution of galaxies.

Black Holes

Cosmic sink-holes or Black Holes is a region of spacetime from which nothing, not even light, can escape. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return. It is called “black” because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics. Quantum mechanics predicts that black holes emit radiation like a black body with a finite temperature. This temperature is inversely proportional to the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass or greater.

Fifty new alien worlds revealed
European astronomers have announced the discovery of more than 50 new planets beyond our solar system, including 16 that are just a notch above our own planet in mass. They say their record-breaking findings suggest that more than half of the stars like our sun possess planets, and that many of those worlds are less massive than Saturn.

The expansion of the universe, the video simulation

The film visualizes what’s said to be the most accurate model for measuring the expansion of the universe. The model, produced at the International Centre for Radio Astronomy Research (ICRAR), in Australia, is based off of the Hubble constant and a massive trove of data on galaxies called the 6dF Galaxy Survey. According to ICRAR:

The 6dF Galaxy Survey has collected more than 120,000 redshifts over the southern sky over a 5 year period from 2001 to 2005. Its goal is to map our southern view of the local universe, and use the peculiar motions of one-tenth of the survey to measure galaxy mass. It covers more than eight times the sky area of the successful 2dF Galaxy Redshift Survey.

Ever wonder where the word “Mesmerized” came from?

Franz Anton Mesmer (May 23, 1734 – March 5, 1815), sometimes, albeit incorrectly, referred to as Friedrich Anton Mesmer, was a German physician with an interest in Astronomy, who theorised that there was a natural energetic transference that occurred between all animated and inanimate objects that he called magnétisme animal (animal magnetism[1]) and other spiritual forces often grouped together as mesmerism. The evolution of Mesmer’s ideas and practices led Scottish surgeon James Braid to develop hypnosis in 1842. Mesmer’s name is the root of the English verb “mesmerize”.
