'Cosmos' Finale Brings a (Big) Bang of Wonder

For astrophysicist Neil deGrasse Tyson, the scientific exploration of our universe is one amazing voyage, and so too has been his run on the new “Cosmos.”

As host of Fox’s science-themed “Cosmos: A Spacetime Odyssey,” Tyson has carried readers back and forth through time, revisited scientists during pivotal discoveries and introduced a new generation to the wonder of space and science. The show debuted in March and airs its 13th and final episode tonight (June 8).

"We end on a note where yes, this is a journey. It’s a look at how far it’s come, look at how much further it can go," Tyson told reporters Friday. “It’s our solar curiosity, if you will, that will keep that pumped. Without it, I don’t know that the country or the world or culture or civilization can go anywhere.”

"Cosmos: A Spacetime Odyssey" is a 21st-century reboot of the iconic 1980 PBS series "Cosmos: A Personal Journey" hosted by the famed astronomer popularizer of science Carl Sagan, who died in 1996. Like that original series, the new show is led by Ann Druyan, Sagan’s widow and longtime partner, who serves as co-writer and executive producer.

But there has been one major difference. This new “Cosmos” has been big. Unlike the 1980 series, which aired on public television, the new “Cosmos” aired Sunday nights on Fox, then again on Monday nights on the National Geographic Channel. The series was beamed out to 181 countries and launched with a tie-in app for mobile devices and well as a vigorous social media campaign.

"I have a feeling that the reaction to the series has exceeded my wildest fantasies," Druyan told Space.com Friday during a conference call. She added that she was stunned last Sunday (June 1), when "Cosmos" came in neck and neck with "The Bachelorette," nearly win the night in ratings with an episode about global warming on Earth.

"I have a feeling of just tremendous satisfaction that Fox and Nat Geo were brave enough to put this show on primetime, which hasn’t happened on a commercial broadcast network such as Fox in recent memory," Druyan said.

Grand Swirls

This new Hubble image shows NGC 1566, a beautiful galaxy located approximately 40 million light-years away in the constellation of Dorado (The Dolphinfish).

NGC 1566 is an intermediate spiral galaxy, meaning that while it does not have a well defined bar-shaped region of stars at its centre — like barred spirals — it is not quite an unbarred spiral either (heic9902o).

The small but extremely bright nucleus of NGC 1566 is clearly visible in this image, a telltale sign of its membership of the Seyfert class of galaxies.

The centres of such galaxies are very active and luminous, emitting strong bursts of radiation and potentially harbouring supermassive black holes that are many millions of times the mass of the Sun.

NGC 1566 is not just any Seyfert galaxy; it is the second brightest Seyfert galaxy known. It is also the brightest and most dominant member of the Dorado Group, a loose concentration of galaxies that together comprise one of the richest galaxy groups of the southern hemisphere. This image highlights the beauty and awe-inspiring nature of this unique galaxy group, with NGC 1566 glittering and glowing, its bright nucleus framed by swirling and symmetrical lavender arms.

today’s episode of Cosmos was amazing! if you’re into Panspermia theory of astrobiology you’ll love this episode. basically getting into how the key ingredients for life lie dorment in orbiting debris like comets, asteroids and other planetary bodies that enter planets and begin the process of evolution and life.

MODEL UNIVERSE RECREATES EVOLUTION OF THE COSMOS

Astronomers have created the first realistic virtual universe using a computer simulation called “Illustris.” Illustris can recreate 13 billion years of cosmic evolution in a cube 350 million light-years on a side with unprecedented resolution.

The computer simulation began a mere 12 million years after the Big Bang. When it reached the present day, astronomers counted more than 41,000 galaxies in the cube of simulated space. 

The model requires a huge amount of computing power: running it on even a state-of-the-art desktop computer would take almost 2,000 years. Even run across more than 8,000 processors, the simulation still took several months.

Scientists.. are human, we have our blind spots and prejudices. Science.. is a mechanism designed to ferret them out. Problem is, we aren’t always faithful to the core values of science.

Herschel Completes Largest Survey of Cosmic Dust in Local Universe

The largest census of dust in local galaxies has been completed using data from ESA’s Herschel space observatory, providing a huge legacy to the scientific community.

Cosmic dust grains are a minor but fundamental ingredient in the recipe of gas and dust for creating stars and planets. But despite its importance, there is an incomplete picture of the dust properties in galaxies beyond our own Milky Way.

Key questions include how the dust varies with the type of galaxy, and how it might affect our understanding of how galaxies evolve.

Before concluding its observations in April 2013, Herschel provided the largest survey of cosmic dust, spanning a wide range of nearby galaxies located 50–80 million light-years from Earth.

The catalogue contains 323 galaxies with varying star formation activity and different chemical compositions, observed by Herschel’s instruments across far-infrared and submillimetre wavelengths.

A sample of these galaxies is displayed in a collage, arranged from dust-rich in the top left to dust-poor in the bottom right.

The dust-rich galaxies are typically spiral or irregular, whereas the dust-poor ones are usually elliptical. Blue and red colours represent cooler and warmer regions of dust, respectively.

'Cosmos: A Spacetime Odyssey' Pulls In 8.5 Million Viewers:

The launch of Fox’s “Cosmos” TV series reboot on 10 different networks Sunday (March 9) attracted in 8.5 million viewers according to a Neilsen ratings summary, the Los Angeles Times reports today. According to the LA Times’ Ryan Faughnder, Fox’s “Cosmos: A Spacetime Odyssey” pulled in a “solid” audience despite tough competition in its 9 p.m. ET/PT time slot

Hosted by astrophysicist Neil deGrasse Tyson, the new 13-part “Cosmos” is a 21st-century follow-up the landmark 1980 series hosted by the famed astronomer Carl Sagan, who died in 1996. Sagan’s series brought the wonder of science and space to the public like never before during its 13-episode run on PBS. The new series aims to capture that same spirit, but include stunning visual effects and new discoveries that are now possible with today’s technology.  [The New “Cosmos”: Complete Coverage]

Cosmos: A Spacetime Odyssey" debuts on 10 different Fox-affiliated networks Sunday night, including Fox Sports 1 and 2, and was re-aired on the National Geographic Channel Monday night with additional material.  Sagan’s widow Ann Druyan — who co-wrote the original "Cosmos" series —serves as a writer and executive producer of the new series. Seth MacFarlane (of "Family Guy" fame among other work) also serves as an executive producer, as does Brannon Braga ("Star Trek" TV franchise). Read the full story from the Los Angeles Times.

Hunt Is On for ‘Rogue’ Black Holes

Hundreds of wandering “rogue” black holes may dwell in the Milky Way — and now researchers say they know how to detect them. Discovering these strange objects could shed light on the formation of the Milky Way and other galaxies.

No one knows exactly how the Milky Way came to exist. But according to one popular model of galaxy formation, the building blocks of the Milky Way were dwarf galaxies that collided and merged shortly after the Big Bang.

This idea assumes that floating black holes, each containing 1,000 to 100,000 more mass than the sun, could be left over from those early cosmic times — fossil evidence for the growth and mergers of black holes in the infant universe.
