On February 23, 2017, the SETI Institute went "Facebook Live" to talk about the newly identified exoplanets named TRAPPIST-1 with SETI Institute researchers Seth Shostak, Franck Marchis, and Susan Thompson, and our CEO Bill Diamond. This is the first time scientists have discovered so many terrestrial planets orbiting a single star – this could be the best target in the galaxy to search for...

Searching for Life on 7 Nearby Alien Worlds: How Scientists Will Do It

The team continues to study the TRAPPIST-1 system with Hubble. But such work can characterize atmospheres only in a relatively broad sense; the hunt for possible signatures of life such as oxygen and methane will require new instruments, the researchers said.

Luckily, such gear will be online soon. NASA's $8.8 billion...

NASA’s New Horizons, IAU Set Pluto Naming Themes

In early 2015, the SETI Institute hosted the “OurPluto” naming campaign, which was endorsed by NASA and the International Astronomical Union (IAU). The goal was to prepare a list of potential categories and names for the surface features on Pluto and its large moon Charon. At the time, New Horizons was speeding toward the Pluto system,...

A Planet Soon to Meet Its Demise

The Kilogree Extremely Little Telescope (KELT) consists of two telescopes — one in Arizona and one in South Africa — that each have a 4.2-centimeter aperture. In total, KELT observes roughly 70% of the entire sky searching for planets transiting bright hosts. And it’s recently found quite an interesting one: KELT-16b. In a publication led by Thomas Oberst...

Layers and Dark Dunes

Much of Mars' surface is covered by fine-grained materials that hide the bedrock, but elsewhere, such as in this scene, the bedrock is well exposed (except where covered by sand dunes).

Colors are enhanced in the cutout of a pit exposing reddish layers.

Winston Churchill and E.T

The context of his ruminations was shaped by the work of astronomer Edwin Hubble and others, who had just shown that the universe was far larger than previously believed. There were not only hundreds of billions of stars populating the galaxy, but vast numbers of other galaxies.

But were there also planets, the presumed habitats for life? In Churchill’s time, the...

A Solar System Found Crowded With Seven Earth-Sized Exoplanets

Seven planets orbiting one star. All of them roughly the size of Earth. A record three in what is considered the habitable zone, the distance from the host star where liquid water could exist on the surface. The system a mere 40 light-years away.

The latest impressive additions to the world of exoplanets orbit the dwarf star...

ICYMI: This weird planetary system seems like something from science fiction (by Seth Shostak)

And indeed, the SETI Institute used its Allen Telescope Array last year to observe the environs of TRAPPIST-1, scanning through 10 billion radio channels in search...

Light curves of the seven TRAPPIST-1 planets as they transit

This diagram shows how the light of the dim red ultra cool dwarf star TRAPPIST-1 fades as each of its seven known planets passes in front of it and blocks some of its light. The larger planets create deeper dips and the more distance ones have longer lasting transits as they are orbiting more slowly. These data were obtained from...

7 Earth-Size Planets Identified in Orbit Around a Dwarf Star

The discovery might also mean that scientists who have been searching for radio signals from alien civilizations might also have been searching in the wrong places if most habitable planets orbit dwarfs, which live far longer than larger stars like the sun.

Mars Life Could Lurk Within These Salty Streaks

Life as we know it requires liquid water. So you can imagine the excitement when, in 2015, hydrated minerals — or compounds that form in the presence of water — were seen on the same Martian slopes as mysterious features known as "recurring slope lineae" or, simply, RSL.

First imaged in high resolution by NASA's Mars Reconnaissance Orbiter...

A Piece of Mars: Who wins in the fight of wind vs. ice? | Lori Fenton's Blog

This is the crest of one of the largest dunes on Mars (0.5×0.5 km or 0.31×0.31 mi). The wind mostly blows from the right, slowly pushing sand up the windward slope. But frost accumulates on (and probably in) the sand during winter, and sometimes it gets too heavy and slides down the steepest slope (toward the left),...

Europa Mission Heralds Sea Change in the Search for Alien Life

After decades of wandering in Martian deserts, NASA’s astrobiologists are at last preparing to rekindle a direct search for a “second genesis” of life in our solar system—but not where one might think. This time, they will look well beyond Mars, the most Earthlike of our planetary neighbors, to the dark reaches of the outer solar...

The brightest, furthest pulsar in the Universe

ESA’s XMM-Newton has found a pulsar – the spinning remains of a once-massive star – that is a thousand times brighter than previously thought possible.

The pulsar is also the most distant of its kind ever detected, with its light travelling 50 million light-years before being detected by XMM-Newton.

Pulsars are spinning, magnetised neutron...
