The Most Intriguing Alien Planet Discoveries of 2017

Scientists spotted seven Earth-size alien planets orbiting one dim red star this year, and a lot of other strange exoplanets — ranging from an Earth-size ice ball to the hottest planet ever found and many more, plus a star that seems to have gobbled up something like 15 rocky worlds. Read on for 2017’s most unusual, fascinating and potentially livable exoplanet finds.

1. The TRAPPIST-1 family

Seven newly discovered, Earth-size planets surround the cool red star TRAPPIST-1, which is slightly larger than the planet Jupiter. Researchers first spotted a few members of its planetary entourage in May 2016 with the TRAnsiting Planets and Planeteslmals Small Telescope (TRAPPIST) in Chile. Additional data from NASA’s Spitzer Space Telescope revealed that rather than three planets, there were seven, all roughly the size of Earth, but orbiting together in a space smaller than Mercury’s orbit around the sun. The fastest and innermost planet, TRAPPIST-1b, whips around the star in just 1.5 days, and the outermost, TRAPPIST-1h, likely takes about 20 days. 
Three of the planets orbit close enough to the star — in what is called the habitable zone — for liquid water to perhaps linger on its surface (but not so close it would have boiled off), but any atmospheres may have been stripped away by the star’s intense radiation.

2. A real scorcher

Astronomers also discovered the hottest planet found to date in 2017 — the Jupiter-like KELT-9b. The planet orbits so close to its star, KELT-9, that it completely circles the star in 1.5 days, and it is tidally locked to the star — meaning the same side is always facing inward. Researchers spotted the planet passing in front of its star with the Kilodegree Extremely Little Telescope (KELT) at Winer Observatory in Arizona.

On that “day side” of the planet, temperatures can reach 7,800 degrees Fahrenheit (4,300 Celsius) — hotter than the surface of a dwarf star, and just 2,200 degrees F (1,200 degrees C) cooler than the surface of the sun. (However, the sun’s outer atmosphere is even hotter.)
KELT-9 is larger and hotter than the sun, and its constant radiation makes KELT-9b’s atmosphere balloon up until it’s half the density of Jupiter. Someday, it may evaporate the planet entirely, researchers said — or, if the planet has a rocky center, boil it down to just the core. Observation with the Hubble and Spitzer space telescopes, as well as the future James Webb Space Telescope, could reveal the planet’s ultimate fate.

3. Home close to home

The alien world Ross 128b, first spotted this year with the High Accuracy Radial velocity Planet Searcher (HARPS) instrument at the La Silla Observatory in Chile, is just 11 light-years from Earth. And although it orbits much closer to its star than Earth does to the sun, the star is cool enough that it could still lie in the habitable zone, if it has a thick enough cover of clouds to reflect away some of the light. Ross 128b is the closest Earth-mass planet potentially in the habitable zone of a quiet star, scientists say — our nearest neighbor, Proxima Centauri, blasts out powerful flares to roast its potentially Earth-size planet, Proxima b.

4. New solar-system rival

Using Google’s machine-learning techniques, scientists found an eighth planet orbiting the star Kepler-90, marking the second eight-planet star system ever found (after Earth’s system, which has eight official planets. Kepler-90i is located 2,545 light-years from Earth, it’s likely rocky, and it’s the third world from its star — but unlike Earth’s 365.26-day orbit, it circles its star in 14.5 Earth days, and is much too close and hot for liquid water to remain on its surface. The planet’s average surface temperatures could reach 800 degrees Fahrenheit (430 degrees Celsius).

The machine-learning program, which also found a planet around another star, made the call by analyzing star-dimming data from the Kepler Space Telescope.

5. Pen pals

Researchers beamed a radio message to the nearby GJ 273 system, which boasts two planets (one potentially in the habitable zone).

Scientists and artists dashed off a messageto the nearby dwarf star GJ 273, which hosts two recently discovered planets. One of them, GJ 273b, could be capable of supporting life — and the system is just 12.36 light-years from Earth.

Team members at METI (Messaging Extraterrestrial Intelligence) International sent a message toward the star using a telescope in Norway, including a scientific and mathematical “tutorial” along with 33 short musical compositions by artists involved with the Sónar Festival in Barcelona. If the message were received, humans could expect a response in under 25 years.

6. Giant snowball

The roughly Earth-size planet 06-OGLE-2016-BLG-1195Lb is a giant iceball under the weak shine of its star.

A newfound alien world 13,000 light-years away with a mouthful of a designation — OGLE-2016-BLG-1195Lb — ha

There are now five different lines of observational evidence pointing to the existence of Planet Nine,” said Konstantin Batygin, a planetary astrophysicist at Caltech in Pasadena.

Some of these clues relate to the gravitational tug of Planet Nine, which appears to be disturbing the distant Kuiper Belt, which is made up of icy objects and stretches from Neptune out into deep space.

Its believed Planet Nine is a “super-Earth”, the name for a type of large world which appears to be very common in the universe.

Doom-mongers have consistently claimed that a hidden world called Nibiru will crash into Earth.

Nasa has denied this theory, previously writing: “The planet in question, Niburu, doesn’t exist, so there will be no collision.

“The story of Niburu has been around for years (as has the ‘days of darkness’ tale) and is periodically recycled into new apocalyptic fables.”

However, it’s feared Planet Nine will eventually destroy the solar system by causing a devastating “death dance”.

It could one day hurtle through our solar system, sending planets “pinballing” into outer space or plunging into the Sun.

David Meade had believers convinced that Earth would be destroyed by Nibiru, or Planet X, on September 23 – but later claimed October 15 and then November 20 is the date to be wary of.

Meade, a Christian conspiracy theorist, has repeatedly warned about a mysterious planet named Planet X or Nibiru on the far edge of our solar system.

Conspiracies suggested it was hurtling towards earth and set to destroy it on September 23.

Now, he claims that people have misunderstood his Planet X prophecy.

Instead, he’s now claiming we could be in for SEVEN years of nuclear war and natural disasters starting on October 15.

Meade says that its “the most important date of this century or millennium”.

October 2017 may signal “the end of the world as we now know it”.

The huge planet will supposedly pull the Earth off its axis, causing earthquakes, storms and widespread chaos.

And the story goes that codes in the Bible and a “date marker” on the Pyramids of Giza, in Egypt, pinpoint the 23rd as the day of reckoning.

However, not everyone is so convinced, with Nasa claiming that the Planet X theory is just a hoax.
