Astronomers may have figured out why alien planets lack exomoons

Astronomers may have figured out why alien planets lack exomoons Astronomers have found a great many exoplanets out there among the stars, but one thing they have not found is exomoons.There’s no evidence of moons orbiting any of the planets we’ve found orbiting other stars, and it’s not clear why.

Asteroid discovered hours before it passes between Earth and moon

Asteroid discovered hours before it passes between Earth and moon While you were sleeping last night, an asteroid passed close to Earth—very close.That’s closer than the orbit of the moon, which is 238,000 miles away.

Scientists want you to help them find planets in this database of stars

Scientists want you to help them find planets in this database of stars So now, researchers are hoping that members of the public will use their free time to comb through and find hints of planets circling those alien suns.By checking out these measurements, scientists can actually learn more about how a star wobbles in its orbit.

How far they'll go: 'Moana' shows the power of Polynesian celestial navigation

How far they'll go: 'Moana' shows the power of Polynesian celestial navigation Moana touches on Polynesian voyaging, showing the eponymous main character using traditional celestial techniques to navigate across the sea.The film accomplished this reasonably well, especially in respect to celestial navigation, despite the producers facing criticism for cultural appropriation and commodification.

Scientists observe first planet-induced stellar pulsations

Scientists observe first planet-induced stellar pulsations But researchers now claim to have found the first example of stellar pulsations caused by an exoplanet.The star HAT-P-2 is emitting visible pulses that seem to be a result of a particularly large exoplanet in a highly eccentric orbit.

7 planets orbiting a star 39 light-years away could play host to alien life

7 planets orbiting a star 39 light-years away could play host to alien life Scientists have discovered that at least seven Earth-sized worlds circle the star TRAPPIST-1, a ultracool dwarf star only about 40 light-years from Earth.Just like Jupiter's moons, the planets orbiting TRAPPIST-1 all interact with one another, meaning that their orbits are influenced by one another.

NASA announces discovery of seven Earth-like exoplanets in a single solar system

NASA announces discovery of seven Earth-like exoplanets in a single solar system NASA has announced the discovery of an amazing planetary system in orbit of a nearby star consisting of seven Earth-like planets in the habitable zone.This was exciting enough to warrant a quick follow up by the Spitzer Space Telescope — TRAPPIST-1’s small size and low temperature was ideal for study with Spitzer’s infrared instruments.

Ripples in space and time carry the future of space science

Ripples in space and time carry the future of space science Billions of years ago, two black holes merged in a violent explosion that rippled the fabric of our universe.Those cosmic ripples — known as gravitational waves — produced by this collision spread far and wide in all directions, carrying with them information about the black holes that brought them into being.

There might be a real-life Tatooine in this distant star system

There might be a real-life Tatooine in this distant star system For the first time, scientists found evidence of a rocky planetary system surrounding a double sun.The star system, which is located about 1,000 light-years from Earth and named SDSS 1557, is composed of a white dwarf star and a brown dwarf — an object too small to be considered a full-fledged star, but too large to be a planet.

NASA gives out data about TRAPPIST-1 and its planets for free online

NASA gives out data about TRAPPIST-1 and its planets for free online Now, NASA is making all of that data freely available online for professional and amateur astronomers.Those dips might be the signals of planets passing between their star and Earth, allowing researchers to learn more about those worlds.

Pocket-sized starshooting camera will ship with a bunch of new lenses

Pocket-sized starshooting camera will ship with a bunch of new lenses That little pocket camera made to shoot the night sky is nearly ready.Photography enthusiasts who want to fit their own lenses on the body will be able to with a C-mount adapter, as well.

Mysterious fast radio bursts might come from alien solar sail spacecraft

Mysterious fast radio bursts might come from alien solar sail spacecraft Astronomers have been puzzling over fast radio bursts (FRB) for the last decade, but there’s not yet any good explanation of these high-energy radio blips.Now that fast radio bursts have defied explanation for this long, scientists are starting to wonder aloud if these extremely high-power emissions could be artificial.

Gorgeous video takes you on a trip above Mars

Gorgeous video takes you on a trip above Mars At the moment, NASA and other space agencies are operating satellites in orbit around Mars.A beautiful new video making use of a high-resolution camera orbiting Mars aboard a NASA spacecraft shows you just that.

Astronomers switch on globe-spanning Event Horizon Telescope

Astronomers switch on globe-spanning Event Horizon Telescope Astronomers around the world have banded together and flipped the switch on a project called the Event Horizon Telescope.Astronomers will use the Event Horizon Telescope to look at two different supermassive black holes.

Scientists find Earth-like planet with an atmosphere just 39 light-years away

Scientists find Earth-like planet with an atmosphere just 39 light-years away That’s where astronomers have discovered an exoplanet called GJ 1132b, which appears to have an atmosphere.The new analysis of GJ 1132b was led by John Southworth, an astrophysicist at Keele University in the UK.

These images show the spectacular results of a star being born

These images show the spectacular results of a star being born A powerful telescope has captured the rainbow-colored remains of an ancient star birth.This story began around 100,000 years ago, when two adolescent protostars (very young stars) grew increasingly angsty about being stuck in their stellar nursery.

Ancient Greeks and Aboriginal Australians saw constellations in common

Ancient Greeks and Aboriginal Australians saw constellations in common The International Astronomical Union recognises 88 constellations, ranging from the giant water-serpent Hydra to tiny Crux (the Southern Cross).In the sky, Orion is defending himself from the charging bull Taurus, represented by the V-shaped Hyades star cluster.

Astronomers spot a massive explosion from the collision of two stars

Astronomers spot a massive explosion from the collision of two stars The Orion Molecular Cloud Complex is a group of nebulae and stellar nurseries positioned some 1,500 light years away from Earth.It says the collision took place 500 years ago, but it takes light from OMC-1 1,500 years to reach us.

Jupiter has a 'Great Cold Spot' to go with its red spot

Jupiter has a 'Great Cold Spot' to go with its red spot Astronomers say the Great Red Spot of Jupiter might have a subtle counterpart currently being called the Great Cold Spot.Seeing the Great Red Spot was a simple matter of building a sufficiently powerful telescope.

Newly Discovered Earth-Like Planet May Have the Right Conditions for Life

Newly Discovered Earth-Like Planet May Have the Right Conditions for Life With every new exoplanet discovery, we seem to get that much closer to finding evidence of extraterrestrial life.A new exoplanet identified in orbit of a nearby star could be the best place to look yet.
