Don’t Cross the (Tidal) Streams

In a tidal disruption event (TDE), an unfortunate star passes too close to a dormant supermassive black hole (BH) and gets torn apart by tidal forces, feeding the BH for a short time. Oddly, we’re not finding nearly as many TDEs — typically detected due to their distinctive observational signatures — as theory says we should. A recent study suggests that we might be missing many of these events, due to the way the streams of shredded stars fall onto the BHs.

The Slumbering Dwarf Awakens: Pluto is about to come back into the limelight (Mark Showalter)

After the busiest July of our lives, the New Horizons team members have finally caught up on sleep. A few of us have even had a chance to take vacations. It’s good that we’re rested up, because an onslaught of new data from Pluto is about to begin.

Right now, 95% of the data obtained during the July 14 flyby is still stored on the spacecraft. After a quiet August, new images will start flowing down to Earth again on Saturday, We will get a few images almost every day.

At Saturn, One of These Rings is not like the Others

In a recent study published in the journal Icarus, a team of Cassini scientists reported that one section of the rings appears to have been running a slight fever during equinox. The higher-than-expected temperature provided a unique window into the interior structure of ring particles not usually available to scientists.

The researchers examined data collected by Cassini's Composite Infrared Spectrometer during the year around equinox. The instrument essentially took the rings' temperature as they cooled. The scientists then compared the temperature data with computer models that attempt to describe the properties of ring particles on an individual scale.

What they found was puzzling. For most of the giant expanse of Saturn's rings, the models correctly predicted how the rings cooled as they fell into darkness. But one large section -- the outermost of the large, main rings, called the A ring -- was much warmer than the models predicted. The temperature spike was especially prominent in the middle of the A ring.

Hell On Earth: NASA Recreates Venus' Extreme Atmosphere | DNews

Scientists interested in studying Venus, as well as other extreme places in the solar system, now have an option besides expensive, one-off space missions. A new test rig at NASA’s Glenn Research Center in Ohio can replicate the planet’s lead-melting temperature, crushing pressure and noxious mix of atmospheric gases to create a similar hell on Earth.

“You don’t have to go Venus now to do Venus atmospheric research,” Daniel Vento, project manager for the Glenn Extreme Environment Rig, or GEER, told Discovery News.

Cosmic Diary: What Self-Luminous Planets are Like | Gemini Planet Imager

When we look at a planet like Jupiter with our eyes, the light that we see is Sunlight that is reflected back to us at Earth, scattered by clouds and gasses in the planet’s atmosphere. But what would Jupiter look like if we instead could see only its thermal “heat” emission, far beyond the visible spectrum? We can use infrared light detectors on telescopes to see this thermal emission, which comes from the deep interior below the visible clouds. We can use this light to precisely “take Jupiter’s temperature” in a way that you can’t do with reflected Sunlight.

Searching for Life … and Death … in the Universe

For over a half century astronomers have been seeking out signs of sentient life in the Search for Extraterrestrial Intelligence (SETI). Now a group of scientists wants to reverse this strategy. Instead of searching for signs of life beyond Earth, they want to hunt for signs of death in the cosmos.

In a paper titled “Observational Signatures of Self-Destructive Civilisations” to appear in the International Journal of Astrobiology, Adam Stevens, Duncan Forgan, and Jack O’Malley-James argue that the next generation of astronomical instruments may be able to detect the remnants of global catastrophes that have wiped out life on distant planets.

Which Galaxies Are the Most Habitable?

A recent study set out to estimate the habitability of a large population of galaxies using three primary factors: total number of stars, metallicity of the stars, and likelihood of Type II supernovae nearby. These factors link together via the "fundamental metallicity relation" which was then used to predict the number of habitable planets in over 100,000 galaxies.

Based on these predictions, the galaxies most likely to host the largest number of habitable planets are those that have a mass greater than twice that of the Milky Way and star formation rates less than a tenth of that of the Milky Way.

#SETITalks - Kepler: Planet Occurence and the Habitable Zone -- Chris Burke

Dr. Burke will discuss latest results in measuring terrestrial planet occurrence rates using the planet candidates discovered by the Kepler pipeline.

For the first time an accurate model for the Kepler pipeline sensitivity to transiting planets is publicly available. Dr. Burke's new analysis finds higher planet occurrence rates and a steeper increase in planet occurrence ratestoward small planets than previously believed.

In addition, Dr. Burke will identify the leading sources of systematics that remain impacting Kepler planet occurrence rate determinations and approaches for minimizing their impact in future studies.

This work also sharpens our understanding on the dependence of planet occurrence rates on stellar effective temperature with potential implications for understanding the planet formation process.

What Happened to Early Mars' Atmosphere? New Study Eliminates One Theory

Scientists may be closer to solving the mystery of how Mars changed from a world with surface water billions of years ago to the arid Red Planet of today.

A new analysis of the largest known deposit of carbonate minerals on Mars suggests that the original Martian atmosphere may have already lost most of its carbon dioxide by the era of valley network formation.

‘No Man’s Sky’ Is the Coolest Video Game Ever

‘No Man’s Sky’ lets players explore space like never before—and is so scientifically accurate that experts are celebrating its (to be announced) release.

The game features 18 quintillion possible planets—all randomly generated, accessible for surveying and unique to the last.

Planetary experts are eager to see their work in a title that looks like it’ll be a blockbuster, judging from a buzz that sometimes reaches hyperspace.

SETI’s Top Astrobiologist Has a Plan to Find Life on Mars

If there were life on Mars, we’d know about it by now. Surely. Right? Not according to Nathalie Cabrol, an astrobiologist at the SETI Institute.

“It’s been so difficult,” she says. “Because we haven’t looked yet!”

Cabrol, who was named head of the Institute’s Carl Sagan Center for the Study of Life in the Universe last month, knows more about (the possibility of) life on Mars than just about anyone else in the world—if not the entire cosmos. She’s been studying the Red Planet for decades; she’s even vacationed there. Well, sorta.

More Spectacular Images from the MUOS-4 Launch

Skywatchers across Central Florida got an unusual view early Wednesday morning in conjunction with the Atlas V launch of the MUOS-4 satellite.

“That wasn’t thunder this AM, Florida: An absolutely stunning MUOS launch!” tweeted photographer Michael Seeley, who shared several images of the launch with Universe Today. Mike is a freelance photographer and works with Spaceflight Insider.

Our mission is to explore, understand and explain the origin, nature and prevalence of life in the universe.
Introduction

We believe we are conducting the most profound search in human history — to know our beginnings and our place among the stars.

The SETI Institute is a private, nonprofit organization dedicated to scientific research, education and public outreach.

The Institute comprises 3 centers, the Center for SETI Research, the Carl Sagan Center for the Study of Life in the Universe and the Center for Education and Public Outreach.

Founded in November 1984, the SETI Institute began operations on February 1, 1985. Today it employs over 120 scientists, educators and support staff. Research at the Institute is anchored by two centers. Dr. Gerry Harp leads the Center for SETI (Search for Extraterrestrial Intelligence) Research and  Dr. David Morrison is the Director for the Carl Sagan Center for the Study of Life in the Universe. Edna DeVore leads our Center for Education and Public Outreach.
