    The larger planets such as Saturn, Jupiter and Uranus remarkably put off more energy than they absorb from our sun. If they were actually in the billions of years of age, should they not have become frozen and expired an incalculable length of time ago. Scientists in this field have come up with many reasons as to the how that these celestial entities kept their heat as far as their theories; however, their noses are firmly planted in a major wall that repels everything they've come up with. Volcanism observed on Jupiter's Io and the geyers with Saturn's Enceladus command...

    Many scientists firmly believe that our universe and Solar System are billions of years old. However, massive data recorded by 50 years' worth of unmanned probes traversing space shows without a doubt that the planets with their moons and comets are actually very young. Our sun powers through its nuclear fuel, and as such it slowly changes constitution. Famed solar astronomer John A. Eddy was quoted, and others in his field believe billions of years ago the sun was dimmer and thus the Earth became a frozen ball. But Mr. Eddy has also recognized that all our information about the...

    Stargazers, get your binoculars ready: a string of bright planets, called a "Planet Parade," will grace the night's sky this week, and the show is expected to last several days. It's just the start of what will be a breathtaking month. A "worm moon" rose on March 1, and another full moon, known as a "blue moon," will pop up on March 31. But this may be the most stunning show yet. A rare parade of planets, including Jupiter, Mars, Saturn, Mercury and Venus along with the bright star Antares, will light the sky starting March 7, though they won't...
  • The Earth's core has a 'jet stream' of molten iron

    12/21/2016 11:18:23 AM PST · by BenLurkin · 21 replies
    You know jet streams as fast-flowing air currents in the atmosphere that can help predict temperature and help planes fly faster. According to data sent back by a trio of ESA satellites called Swarm, though, there's also a jet stream deep beneath our planet's surface, and it's made of molten iron. A team of European scientists have discovered the jet stream in the Earth's outer core that's located 1,900 miles underneath its crust. It moves at 25 miles per year, three times faster than the speed of the other layers in the outer core and a thousand times faster than...

    Jupiter and Venus will pair up in the sky on Monday morning, shining brightly together shortly before sunrise. The two planets will appear so close together that they may look like they are just one bright star rather than two planets. This is the closest these two planets will appear all year, an astronomical event known as a conjunction. Venus and Jupiter may appear very close to each other in the morning sky, but they are actually more than 400 million miles away from each other. Venus and Jupiter will rise together about one hour before sunrise in the eastern...

    In the hostile environment of the ‘galactic bulge’ at the heart of our galaxy, scientists have spotted a planet so big it might not actually be a planet. A large international team of researchers found the object when looking at data acquired by NASA’s Spitzer infra-red space telescope, which was first launched in 2003. Using a technique called micro-lensing, which measures distortions in light when a star passes in front of another, scientists were able to discover the mysterious object is 22,000 light years away from Earth, and orbits its parent star roughly every three years. Dubbed OGLE-2016-BLG-1190Lb, the object...

    Unusual composition of star suggests it swallowed planets that came too closeIt was a star with a hefty appetite. Astronomers say the sun-like star about 320 light-years from Earth may have eaten several of its planets, leading them to give it the nickname Kronos, after the Greek god who ate his sons. The star — with the official name of HD 240430 — is believed to be part of a wide binary star system, two stars that share a central point of orbit. Because the stars travel together in space, astronomers refer to them as co-moving stars. While the stars...

    With scalding surface temperatures of a hellish 4,327°C, researchers have discovered the hottest planet ever found. The planet, named KELT-9b, is 650 light years away, and so close to its host star its orbit takes just a day and a half. Researchers hope their findings will shed light on how planetary systems form around hot, massive stars.

    Early science results from NASA’s Juno mission to Jupiter portray the largest planet in our solar system as a complex, gigantic, turbulent world, with Earth-sized polar cyclones, plunging storm systems that travel deep into the heart of the gas giant, and a mammoth, lumpy magnetic field that may indicate it was generated closer to the planet’s surface than previously thought. “We are excited to share these early discoveries, which help us better understand what makes Jupiter so fascinating,” said Diane Brown, Juno program executive at NASA Headquarters in Washington. "It was a long trip to get to Jupiter, but these...

    Real Clear Science ^ | February 27, 2017 | Ross Pomeroy
    The International Astronomical Union currently defines a planet as: "a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighborhood around its orbit." A newly suggested definition takes a different approach:

    Planet-hunters are always on the lookout for worlds that look like Earth—rocky planets that are not too hot and not too cold for liquid water to flow on the surface. Now scientists have hit the jackpot, discovering seven Earth-size exoplanets orbiting a single star just 39 light-years away. The star, named TRAPPIST-1, was thought to be home to three exoplanets. But with the help of a variety of observatories—including the Transiting Planets and Planetesimals Small Telescope (a.k.a. TRAPPIST, the star's namesake), the Very Large Telescope in Chile, and NASA's Spitzer Space Telescope—researchers found four more planets in the system. The...

    The hunt for potentially habitable planets outside of our solar system is one of the most exciting frontiers of science, and you can become a part of it without ever having to leave the comfort of your own home. This week, MIT and Carnegie Science Institute released a huge dataset containing close to 61,000 measurements of over 1600 stars. These measurements contain data that could potentially identify thousands of new exoplanets, many of which might be Earth-like in their nature. Unfortunately, the MIT and Carnegie Institute team simply doesn’t have the capacity to trawl through all of this information,...

    By 2025 Elon Musk believes SpaceX can get us to Mars – a journey of about 500 million kilometres, needing a speed of over 100,000 km/h. By comparison travelling to the stars within a human lifetime via the known laws of physics requires energies millions of times more potent than that budget-price trip to Mars. In our energy hungry modern world the prospect seems fanciful, yet we are surrounded by energies and forces of comparable scale. By taming those forces we will be able to launch forth towards the stars, save our civilization and extend the reach of our biosphere....

    Astronomers monitoring the Kepler space telescope have detected nearly 1,300 planets flying in orbit around distant stars, a cosmic search that began nearly 10 years ago inside a rusty old telescope dome at the Lick Observatory atop Mount Hamilton near San Jose. From the size and orbits of the new-found “exoplanets,” the astronomers said at least 550 could be rocky planets much like Earth, and at least nine are orbiting at just the right distance from their stars to lie inside their “habitable zones” where temperatures would be just right for liquid water, the one ingredient essential for life to...

    Rare Jewel: Earth-like Planets May Be Very Rare Msgr. Charles Pope • February 28, 2016 • I have written a good bit over the years about what is known as the “Rare Earth” Hypothesis. A recent blog on discovermagazine.com ponders how high the odds are against the existence of another Earth-like planet. More on that in a moment. But first let’s review some of the basics of the Rare Earth Hypothesis.While most people, including most scientists, believe that there may be billions of inhabitable planets out there a capable of sustaining complex life, the Rare Earth Hypothesis suggests that...

    Phys.org ^ | January 20, 2016 | Kimm Fesenmaier
    Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun at an average distance of 2.8 billion miles). In fact, it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the sun. The researchers, Konstantin Batygin and Mike Brown, discovered the planet's existence through mathematical modeling...
