VISALIA - The opera "The planets" may have launched composer Gustav Holst's career into orbit but its popularity seemed to pull his spirits down. According to Holst biographers, the piece was a triumph of his time, in tune with his contemporaries and grounded in lifelong themes of mankind's duality of war ...

When scientists searching for exoplanets -- worlds located beyond our solar system -- first spotted patterns in disks of dust and gas around young stars, they thought newly formed planets might be the cause. But a recent NASA study cautions that there may be another explanation -- one that doesn't ...
"The similar sizes and orbital spacing of planets have implications for how most planetary systems form," researchers said in the statement. "In classic planet-formation theory, planets form in the protoplanetary disk that surrounds a newly formed star. The planets might form in compact configurations with ...
As Calla Cofield at Space.com reports, while software is able to identify stars that host planets, it still takes a human to confirm the data. So scientists turned to citizen scientists for help, developing Exoplanet explorers, hosted on the Zooniverse platform--a system that connects citizen scientists to projects.
A family of four planets orbiting a distant star was discovered last April, with the help of citizen scientists around the world. In a new paper, researchers reveal some fascinating features of this alien solar system, including the presence of a fifth planet. The planetary system K2-138 is home to at least five ...

planets form out of the same natal gas as their parent star. So a star's high metallicity is a sign that its planets came together within metal-enriched gas. Previous studies have found that metallicity plays a role in planet formation -- but Astronomers don't yet understand how the connection works.
Generally, the disk of planet-forming material surrounding a sun-like star condenses to form planets and moons within a few million years of the star's birth. However, a large amount of gas and dust still circles RZ Piscium, which suggests the star is destroying planets in its vicinity, rather than building them.
View larger. | Dennis Chabot of POSNE NightSky Astrophotography caught Jupiter and Mars on January 7, 2018, the day of their spectacular conjunction. On that morning, these 2 planets were about half a moon-diameter apart. In all the photos on this page, Jupiter is the brightest "star" visible. It's also now ...
SpaceX CEO Elon Musk was interested in getting a newly elected President Donald Trump on board with his company's mission to explore other planets, according to an excerpt from a new book on the Trump Administration that has dominated headlines this week. Among the many claims made in Michael ...
Because multiple systems are common, they may be rich targets in the hunt for alien planets, according to Ruslan Belikov, an astrophysicist at NASA's Ames Research Center in Moffett Field, California, and his colleagues. For example, the sun's closest neighbor, the Alpha Centauri system, possesses three ...

Among the many claims made in Michael Wolff's "Fire and ...
The planets will then make their way over the sky at an altitude of 22 degrees above the southern horizon before the break of dawn at 7.37am washes them away. Royal Observatory Greenwich said: "A little before dawn Jupiter and Mars will be very close in the night sky, about one fifth of the width of your ...
As a result, early discoveries--such as the first exoplanet to be found, in 1995--were usually "hot Jupiters," giant planets in tight orbits. Then came the High Accuracy Radial velocity Planet Searcher (HARPS) at ESO's La Silla Observatory in Chile in 2003, a second-generation spectrograph that enabled ...
"We used machine learning to help identify planets that were missed by previous searches of the Kepler data," Christopher Shallue, a senior software engineer with Google's research team Google AI, said during a Dec. 14 conference call. "Machine learning really shines in situations where there is too ...
It currently pays to be an early riser if you wish to view the planets, for it's all happening at dawn in the skies of Western Europe. Observers in the UK wishing to get the best views should find a location that offers an unobstructed southeasterly aspect where, if you are blessed with clear skies between 7am ...
"Until 2013, rings were only known around giant planets," the authors wrote in the paper. "This discovery was thus surprising, and is key to better understanding the planetary rings, since [small-object ring systems] now appear to be more common than previously thought." [asteroid Chariklo Has Rings: ...

The American space agency NASA and the technology company Google have identified an eighth planet in a faraway solar system. That solar system now has exactly the same number of planets as our own. Machines made the surprising discovery, not human researchers. NASA and Google ...
Study co-author Catherine Pilachowski said: "We know it's not uncommon for planets to migrate inward in young solar systems since we've found so many solar systems with 'hot Jupiters'--gaseous planets similar in size to Jupiter but orbiting very close to their stars. "This is a very interesting phase in the ...
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 ...
A team of U.S. Astronomers said on December 21, 2017 that they've found evidence suggesting the strange, unpredictable dimming episodes of the star RZ Piscium might be caused by vast orbiting clouds of gas and dust, the remains of one or more destroyed planets. This star is located about 550 ...
(CNN) For the first time, eight planets have been found orbiting a distant star, Kepler-90, 2,545 light-years from Earth in the Draco constellation, NASA announced Thursday. It is the first star known to support as many planets as are orbiting our own sun, and researchers believe that this is the first of many to ...
Kepler has identified 2,525 planets so far, and more are likely waiting to be found in the data. But it's not an easy task to confirm a planet as real. Sorting through the massive amount of Kepler data by hand is an impossible task for humans--those data contain several quadrillion possible planetary orbits.
The idea of life on other planets is old and can be traced back to ancient times, but until just a few years ago this was all it was--an idea. The breakthrough occurred in 1995 when we discovered the first exoplanet--a planet in orbit around another star. Suddenly, we were a little less alone in the universe.
The two visible planets, Mars and Jupiter, are remarkably close together in the morning sky. They are less than one degree apart going into the weekend. If you happen to be outside at 5 o'clock or earlier in the mornings ahead take a good look. The proximity of the two dazzles the imagination. They look ...
The last thing the planets around the red dwarf star TRAPPIST-1 need is abundant sunshine. Active eruptions and flares from the star would wreak havoc on the rocky planets in orbit. But fortunately, the outer planets might be safe from this barrage of high-energy space weather. According to a new study in ...
Ancient Arab accounts tell of a mysterious temple in eastern Anatolia dedicated to the planets. The ruins surrounding the modern village of Sogmatar used to be an important city during the Hellenistic Period. It was a center for the worship of the moon and the planets. The site contains an impressive ...
The star system is particularly interesting because it's believed life could spread between some of its planets by floating through the void of space on comets or asteroids, a process known as panspermia. Could this mean aliens are living on one of the seven exoplanets orbiting the star? Perhaps.
Three planets will form a cosmic conga line with the moon in March. Skychart by A. Fazekas. Early risers in late February and into early March will be able to watch a planetary alignment dominate the southeastern sky at dawn, as Saturn, Mars, and Jupiter will seem to hover near each other in the sky.
Professor Pilachowski said: "Based on our observations, it seems either that we're seeing a fairly massive, gaseous planet being pulled apart by the star, or perhaps two gas-rich planets that have collided and been torn apart." The research is responsible for determining the gravitational strength near RZ ...

Our solar system is the sun and everything orbiting it, including planets. We have eight in our solar system, and you can see five without the aid of a telescope. Surrounding the planets in the sky are thousands of stars that are part of our galaxy, but not our solar system. Do any of these stars have orbiting ...
Astronomers think the erratic dimming of a distant star may be caused by the orbiting remains of planets it has "consumed". Stars normally shine brightly and consistently, but RZ Piscium - found 550 light years away in the constellation Pisces - is prone to unpredictable and previously unexplained periods ...
"We know it's not uncommon for planets to migrate inward in young solar systems since we've found so many solar systems with 'hot Jupiters' -- gaseous planets similar in size to Jupiter but orbiting very close to their stars," said Pilachowski, who is the Daniel Kirkwood Chair in the IU Bloomington College of ...
Google is famous for its "20 percent time," whereby staffers are allowed to spend the equivalent of one workday a week on passion projects that they believe will benefit the company. The idea is that creativity and innovation happen when people are allowed to experiment. Things such as gmail and ...

Sorting through the massive amount of Kepler data by hand is an impossible task for humans--those data contain several quadrillion possible planetary orbits.
It did not take long before several books were published speculating about what sort of life might exist on the planets. Some authors assumed ...
Close to the sun orbit four rocky planets - mercury, Venus, Earth and Mars. Further out are four giants - Jupiter, Saturn, Uranus and Neptune.
scientists thought the 1930 discovery of pluto was a once-in-a-lifetime feat but we've discovered 3,500 potentially habitable planets since.
The ice-giant planets weren't discovered until the invention of the telescope because they are not readily visible to unaided eyes. But with ...
