A couple of things to note in the image. The colors are vivid but as this news release explains,
they are purely for illustrative purposes. We have little data on the color of any of these worlds with the exception of HD 189733b,
sometimes called the ‘blue planet.’ The cloud patterns shown here are also theoretical, based largely on what we see on Jupiter.

ET's not talking—and we want to know why. Here are some possible explanations.

ESOcast 79: 20 Years of Exoplanets


Published on Dec 8, 2015 Not a single confirmed planet outside the Solar System had been detected before the year 1990.
But, remarkably, we now know of thousands and have studied many in surprising detail.
This ESOcast takes a look at how ESO’s observatories in Chile have been at the forefront of this enormous expansion in knowledge,
and how their state-of-the-art instruments are continuing to discover and study the extraordinary diversity of exoplanets.

Home/News/An Earth-like extrasolar planet could harbor extraterrestrial life


Figure 1. This planet could be an important discovery in the search for life on other planets By Nicole Kiefert | Published: Monday, November 28, 2016 Researchers from the Astronomical Observatory of Japan (NAOJ), the University of Tokyo, and the Astrobiology Center have nailed down an important property of a potentially Earth-like extrasolar planet while it was in transit. The team used the MuSCAT instrument on the Okayama Astrophysical Observatory’s 188-cm telescope to study the extrasolar planet, called K2-3d, discovered by NASA’s Kepler spacecraft in 2015.

Figure 2: Transiting planets located in the habitable zone (the orbital region where a planet could hold liquid water on the surface), plotted in terms of planet radius vs. host star magnitude (brightness). Black circles represent confirmed planets discovered by the Kepler mission and white circles represent unconfirmed planet candidates. The orange triangles represent the Earth sized planets TRAPPIST-1c and TRAPPIST-1d observed 40 light-years away by a ground based telescope. TRAPPIST-1c and TRAPPIST-1d are thought to be just outside the habitable zone, but they are plotted for reference. The host star of K2-3d (red star) is the brightest in this figure.

Figure 3: Predicted transit time deviation from the improved K2-3d transit ephemeris based on this research. The solid red line indicates the predicted times based on this research, the shaded area shows the uncertainty range. Squares, triangles, and circles are respectively the transit time data from the Kepler Telescope, Spitzer Space Telescope, and the latest observing instrument MuSCAT on the Okayama 188-cm Reflector Telescope. Gray marks show the values calculated in previous research and black marks represent the values re-calculated in this research. Purple and orange dotted lines are the transit ephemerides calculated in previous research using the K2 and the K2+Spitzer data, respectively.

Exoplanet β Pic b orbiting β Pictoris from Dunlap Institute on Vimeo.

A series of images taken between November 2013 to April 2015 with the Gemini Planet Imager (GPI) on the Gemini South telescope in Chile shows the exoplanet β Pic b orbiting the star β Pictoris, which lies over 60 light-years from Earth. In the images, the star is at the centre of the left-hand edge of the frame; it is hidden by the Gemini Planet Imager’s coronagraph. We are looking at the planet’s orbit almost edge-on; the planet is closer to the Earth than the star. The images are based on observations described in a paper published in the Astrophysical Journal, 16 September 2015 and whose lead author is Maxwell Millar-Blanchaer. GPI is a groundbreaking instrument that was developed by an international team led by Stanford University’s Prof. Bruce Macintosh (a U of T alumnus) and the University of California Berkeley’s Prof. James Graham (former director of the Dunlap Institute for Astronomy & Astrophysics, U of T).

Wolf 1061c The planet, more than four times the mass of the Earth, is one of three that the team detected around a red dwarf star called Wolf 1061.
"It is a particularly exciting find because all three planets are of low enough mass to be potentially rocky and have a solid surface,
and the middle planet, Wolf 1061c, sits within the 'Goldilocks' zone where it might be possible for liquid water --
and maybe even life -- to exist," says lead study author UNSW's Dr. Duncan Wright.

Video News File: Kepler Discovers First Earth-size Planet in the Habitable Zone of Another Star


Published on Apr 17, 2014 [Video News File; media resource preview] NASA's Kepler Space Telescope has discovered the first validated Earth-size planet orbiting in the habitable zone of a distant star,
an area where liquid water might exist on its surface. The planet, Kepler-186f, is ten percent larger in size than Earth and orbits its parent star,
Kepler-186, every 130 days. The star, located about 500 light-years from Earth, is classified as an M1 dwarf and is half the size and mass of our sun.

The graphic tells NASA's Kepler spacecraft's story by the numbers from the moment it began hunting for planets
outside our solar system on May 12, 2009. From the trove of data collected, we have learned that planets are common,
that most sun-like stars have at least one planet and that nature makes planets with unimaginable diversity.

NASA | 'Disk Detectives' Top 1 Million Classifications in Search for Planetary Habitats


The Companion DIsk detective.org

Published on Jan 6, 2015
Citizen scientists using the NASA-sponsored website DiskDetective.org have logged 1 million classifications
of potential debris disks and disks surrounding young stellar objects (YSO). This data will help provide a crucial set of targets for
future planet-hunting missions. By combing through objects identified in an infrared survey made with NASA's Wide-field Infrared Survey Explorer (WISE) mission,
Disk Detective aims to find two types of developing planetary environments: YSO disks, which are less than 5 million years old and contains
large quantities of gas, and debris disks, which tend to be older than 5 million years, and contain belts of rocky or icy debris.

Artist’s impression shows a sunset seen from the super-Earth Gliese 667 Cc

Is there life on other planets, somewhere in this enormous Universe? That’s probably the most compelling question we can ask.
A lot of space science and space missions are pointed directly at that question. The Kepler mission is designed to find exoplanets, which are planets orbiting other stars. More specifically,
its aim is to find planets situated in the habitable zone around their star. And it’s done so.
The Kepler mission has found 297 confirmed and candidate planets that are likely in the habitable zone of their star,
and it’s only looked at a tiny patch of the sky.

Light Echoes Give Clues to Protoplanetary Disk

This illustration shows a star surrounded by a protoplanetary disk. Material from the thick disk flows along
the star’s magnetic field lines and is deposited onto the star’s surface. When material hits the star, it lights up brightly.
The star's irregular illumination allows astronomers to measure the gap between the disk and the star by using a
technique called "photo-reverberation" or "light echoes." First, astronomers look at how much time it takes for light from
the star to arrive at Earth. Then, they compare that with the time it takes for light from the star to bounce off the
inner edge of the disk and then arrive at Earth. That time difference is used to measure distance, as the speed of light is constant. Image credit: NASA/JPL-Caltech Last Updated: April 26, 2016 Editor: Tony Greicius

Astronomers can use light echoes to measure the distance from a star to its surrounding protoplanetary disk.
This diagram illustrates how the time delay of the light echo is proportional to the distance between the star
and the inner edge of the disk. Credits: NASA/JPL-Caltech

The Kepler 80 system


Image: This animation shows the position of the five planets of Kepler-80 whenever the outer two planets (green and red) pass by one another, about every 27 days
over the course of four years of observations by NASA’s Kepler Space Telescope. Due to the rare synchronized nature
of the system, the middle two planets (blue and purple) also return to almost exactly the same location.
The innermost planet (yellow) is not synchronized and hence is found at a random location every 27 days.
MacDonald et al. 2016 were able to show that this pattern indicates formation by “migration,”
where the orbits shrink very slightly over time. The orbits are to scale with each other, but the planets are shown 50 times larger.
The outer four planets are all about 4-6 times the mass of the Earth. The inner three planets ( blue, purple, and yellow) appear rocky and the outer two planets (green and red ) are likely rocky with a very puffy Hydrogen/Helium atmosphere. Credit: MacDonald/Ragozzine/FIT.

Kepler-223 star system has four mini-Neptunes in synchronised orbits


Orbital evolution in Kepler-223


Published on May 11, 2016 These animations show approximately 200,000 years of orbital evolution in the Kepler-223 planetary system.
The planets’ interactions with the disk of gas and dust in which they formed caused their orbits to shrink
toward their star over time at differing rates. Once two planets reach a resonant state (for example, one planet orbits
its star three times every time the next planet orbits two times), the planets strongly interact with each other.
The interactions become apparent in the animations as the orbits shrink (left and top right) when the orbital period ratios of
neighboring planets (bottom right) get stuck at constant values. Even as the planets continue moving inwards (upper right) they do
so in concert, migrating together locked in this configuration. They also cause each other’s orbits to change from nearly circular to elliptical.
This is represented by the varying orbits on the left panel and the spread of the orbital distances for each individual planet in the upper right.

Rare 4-planet system discovered by Kepler UC Berkeley


Published on May 12, 2016 For the full story, visit: A four-planet system observed several years ago by the Kepler spacecraft is actually a rarity: Its planets, all miniature Neptunes nestled close
to the star, are orbiting in a unique resonance that has been locked in for billions of years. For every three orbits of the outermost planet,
the second orbits four times, the third six times and the innermost eight times. Such orbital resonances are not uncommon – our own dwarf planet Pluto orbits the sun twice during the same period that Neptune completes
three orbits – but a four-planet resonance is. Astronomers from the University of Chicago and University of California, Berkeley, who are reporting the discovery online May 11
in Nature, are particularly interested in this stellar system because our system’s four giant planets –
Jupiter, Saturn, Neptune and Uranus – are thought to have once been in resonant orbits that were disrupted sometime during their 4.5-billion-year
history. According to co-author Howard Isaacson, a UC Berkeley research astronomer, the Kepler-223 star system can help us understand how our solar system
and other stellar systems discovered in the past few decades formed. In particular, it could help resolve the question of whether planets stay
in the same place they formed, or whether they move closer to or farther from their star over the eons.

HD 131399Ab – an exoplanet with three suns

Published on Jul 7, 2016 Some 320 light-years away from Earth, in the constellation of Centaurus (The Centaur),
the planet HD 131399Ab orbits around a star in a triple-star system. HD 131399Ab
is about 16 million years old, one of the youngest exoplanets discovered to date,
and has an estimated mass of four Jupiter masses. An observer on HD 131399Ab would either
experience constant daylight or enjoy triple sunrises and sunsets each day, depending on the seasons,
which last longer than human lifetimes. Credit: ESO/Digitized Sky Survey 2/N. Risinger (skysurvey.org) ESO/L. Calçada/M. Kornmesser ESO/K. Wagner et al. ESO/L. Calçada

That’s a useful insight because we have no other information about the nature of these planets.
Their masses have not been measured, and we have no other data about the kind of planets that can exist
around ultracool dwarf stars (TRAPPIST-1 is an M8 dwarf) because the TRAPPIST-1 worlds are our first transiting example.
The excerpt below shows the team’s reasoning, building on the fact that the lack of features in the combined spectrum
rules out certain kinds of atmospheres:

Image: The binary transit visualized. Credit: NASA/ESA/STScl. With an extended gas envelope ruled out, we wind up with a range of possible atmospheres,
ranging from the CO2-dominated Venus to an Earth-like atmosphere with heavy clouds or a depleted atmosphere
like what we see on Mars. To push further into the possibilities, the team has formed a consortium called
SPECULOOS (Search for habitable Planets Eclipsing ULtra-cOOl Stars), the good news being that they are building
larger versions of the TRAPPIST instrument in Chile that will focus on the brightest ultracool dwarf stars in the southern hemisphere.
Consider the effort an attempt to build the kind of pre-screening tools that our future space telescopes like the
James Webb instrument will need for their target list. The paper is de Wit et al., “A combined transmission spectrum of the Earth-sized exoplanets TRAPPIST-1 b and c,” Nature 20 July 2016 (preprint).

NASA & TRAPPIST-1: A Treasure Trove of Planets Found

Published on Feb 22, 2017 Seven Earth-sized planets have been observed by NASA's Spitzer Space Telescope around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1. Three of these planets are firmly in the habitable zone. Over 21 days, NASA's Spitzer Space Telescope measured the drop in light as each planet passed in front of the star. Spitzer was able to identify a total of seven rocky worlds, including three in the habitable zone, where liquid water might be found. The video features interviews with Sean Carey, manager of the Spitzer Science Center, Caltech/IPAC; Nikole Lewis, James Webb Space Telescope project scientist, Space Telescope Science Institute; and Michaël Gillon, principal investigator, TRAPPIST, University of Liege, Belgium. The system has been revealed through observations from NASA's Spitzer Space Telescope and the ground-based TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, as well as other ground-based observatories. The system was named for the TRAPPIST telescope. NASA's Jet Propulsion Laboratory, Pasadena, California, manages the Spitzer Space Telescope mission for NASA's Science Mission Directorate, Washington. Science operations are conducted at the Spitzer Science Center at Caltech in Pasadena. Spacecraft operations are based at Lockheed Martin Space Systems Company, Littleton, Colorado. Data are archived at the Infrared Science Archive housed at Caltech/IPAC. Caltech manages JPL for NASA.

Flying through the Ross 128 planetary system

This artist’s impression video shows the temperate planet Ross 128 b along with its red dwarf parent star. This planet, which lies only 11 light-years from Earth, was found by a team using ESO’s unique planet-hunting HARPS instrument. The new world is now the second-closest temperate planet to be detected after Proxima b. It is also the closest planet to be discovered orbiting an inactive red dwarf star, which may increase the likelihood that this planet could potentially sustain life. Ross 128 b will be a prime target for ESO’s Extremely Large Telescope, which will be able to search for biomarkers in this planet’s atmosphere. More information and download options:

This zoom video sequence takes the viewer towards the sprawling constellation of Virgo (The Virgin). The first thing we encounter on our journey is the faint red dwarf star Ross 128, just 11 light-years from the Earth and the closest object in the constellation of Virgo.
