The Discovery of Exoplanets

Exoplanets are planets that obit a different star other than our Sun - in a different solar system to the one we are in.Even though scientists thought for a long time that they must exist, it was only in 1992 that the first exoplanet was discovered.Earlier in 2015, scientistsdiscovered the exoplanet Kepler-452b,which was described as 'earth's cousin' because of its close similarities to our planet.Space experts say Exoplanets are really important because they raise the possibility that other life could exist in other solar solar systems.

Pluto has blue skies and patches of frozen water on its surface

Blue skies are seen on Earth because of the scattering of sunlight by very small particles of nitrogen."On Pluto they appear to be largerbut still relatively smallsoot-like particles we call tholins," said science team researcher Carly Howett, also of SwRI.Using a tool called a spectral composition mapper on New Horizons, scientists have been able to map the signatures of water ice on various parts of the planet's surface.

Saturn's Moons and Rings Are Younger Than the Dinosaurs

Some of Saturn's icy moons may have been formed after many dinosaurs roamed the Earth. New computer modeling of the Saturnian system suggests the rings and moons may be no more than 100 million years old.

Belt Of Venus' Glows Over Paranal Observatory..

On May 9,after the transit of Mercury dazzled the world, Discovery Newswas attending the #MeetESO event atop Cerro Paranal, a 2,664 meter (8,740 ft) high mountain in the Atacama Desert in northern Chile on the platform of the VLT. As the sun set over the desert clouds below, the Belt of Venus rose over the VLTs auxiliary telescopes behind us as the observatorys 4 main 8.2 meter telescope domes opened.

Geysers on Saturn Moon Enceladus Hint at Plumbing Mystery..

A small water jet on Enceladus, an icy moon of Saturn, spews its fiercest eruptions when the moon is farthest from the planet, a new study suggests, but the overall gas output doesnt increase much during that time. The study points to a mystery in Enceladus plumbing.The surprise observation came after looking at the moon usingthe Saturn-orbiting Cassini spacecraftin March. Enceladus is considereda prime potential location for lifebecause under its icy surface is a global, salty water-ocean that could have the right ingredients for microbes.

Another Kuiper Belt Discovered Around Nearby Star.

Astronomers have discovered an icy belt of comets circling a young sun-like star, a finding that may provide insights into the evolution of our own solar system.The star, known as HD 181327, is about 23 million years old and located about 160 light-years away in the Painter constellation.

"Milky Way's Dark Disk" --Did It Seed Existence of the Central Supermassive Black Hole?

The composite Hubble Space Telescope, Spitzer Space Telescope, and the Chandra X-ray Observatory image of the central region of our Milky Way galaxy above shows the center of the galaxy. Like the downtown of a large city, the center of our galaxy is a crowded, active, and vibrant place. The supermassive black hole -- some four million times more massive than the Sun -- resides within the bright region in the lower right.

Advanced Alien Life? SETI Retargets "Pale Red Dots Billions of Years Older Than Our Sun"..

The SETI Institute belives that planetary systems orbiting red dwarfs - dim, long-lived stars that are on average billions of years older than our sun are worth investigating for signs of advanced extraterrestrial life. The star thats closest to our sun, Proxima Centauri, is a red dwarf. A variety of observing efforts, including the University of London'sPale Red Dot Initiative, are looking for earthlike habitable planets around Proxima Centauri .Red dwarfs the dim bulbs of the cosmos have received scant attention by SETI scientists in the past, SETI Institute engineer Jon Richard said last March announcing a new initiative. Thats because researchers made the seemingly reasonable assumption that other intelligent species would be on planets orbiting stars similar to the sun.

"Europa's Ocean Chemistry and Energy May Hold the Elixir for Life..

"The cycling of oxygen and hydrogen in Europa's ocean will be a major driver for Europa's ocean chemistry and any life there, just it is on Earth." Ultimately, Vance and colleagues want to also understand the cycling of life's other major elements in the ocean: carbon, nitrogen, phosphorus and sulfur.The ocean of Jupiter's moon Europa could have the necessary balance of chemical energy for life, even if the moon lacks volcanic hydrothermal activity, finds a new study. Europa is strongly believed to hide a deep ocean of salty liquid water beneath its icy shell.

Monster Earth Impact --"Evidence Found of a Huge Asteroid 20-to-30 Kilometers Across

Scientists have found evidence of a huge asteroid 20 to 30 kilometers across that struck the what is today Australia, creating a 400 kilometer-wide impact zone after breaking in two moments before it slammed into the Earth. The impact crater has long since disappeared. But a team of Aussie geophysicists has found the twin scars of the impacts the largest impact zone ever found on Earth hidden deep in the earths crust.Large impacts like these may have had a far more significant role in the Earths evolution than previously thought, Glikson said.

The Milky-Way Planet That's Three Times Older Than Earth.

The existence of a 13-billion year old planet, if in fact it still exists, highlights the fact that our Solar System exists in a universe that is estimated to be between 13.5 and 14 billion years old. A few intrepid astronomers have concluded that the most productive to look for planets that can support life is around dim, dying stars white dwarfs so prevalent inglobular cluster M4shown above."Even dying stars could host planets with life - and if such life exists, we might be able to detect it within the next decade. This encouraging result comes from a new theoretical study of Earth-like planets orbiting white dwarf stars.
