today’s holiday: Roman Games

Roman Games

Like the Plebeian Games, the Roman Games were held in honor of Jupiter. They date back to the dedication of the temple to Jupiter on the Capitoline hill on September 13, 509 BCE. Originally a one-day event, by the time of Caesar the Games lasted a full 15 days beginning on September 4. A grand procession to the Circus Maximus, a huge arena just outside Rome, signalled the beginning of the festival. Events included boxing, running, and wrestling contests, occasional mock battles, and two- and four-horse chariot races. More… Discuss


Space: the final frontier: Spacecraft Will Be First to Visit Dwarf Planet

Spacecraft Will Be First to Visit Dwarf Planet

NASA’s unmanned Dawn spacecraft will soon be visiting a planet that you’ve probably never heard of: Ceres, a dwarf planet in the asteroid belt between Jupiter and Mars. When it arrives March 6, Dawn will become the first spacecraft to visit one of the five dwarf planets, whose ranks include the former planet Pluto. Ceres was likely becoming a full-sized planet before Jupiter stunted its growth 4.6 billion years ago. It is now the largest object between Mars and Jupiter, and the largest object between the Sun and Pluto that has not yet received a visit from Earth. More… Discuss

today’s holiday: Juturnalia (2015)

Juturnalia (2015)

According to Virgil, Juturna is the sister of Turnus, king of the Rutuli. In return for her virginity, Jupiter gave her immortality. Afterward, she was turned into a fountain of the same name near the Numicus, the river where Aeneas’ dead body was found. The waters from this fountain were used in sacrifices, particularly those in honor of the Roman goddess Vesta, and were believed to have curative powers. On January 11, a festival in honor of Juturna was observed by men working on aqueducts and wells. She was also celebrated at the Vulcanalia on August 23 as a protectress against fire. More… Discuss

this day in the yesteryear: Jupiter’s Io Observed by Spacecraft Galileo (2001)

Jupiter’s Io Observed by Spacecraft Galileo (2001)

Discovered by Galileo Galilei in 1610, Io is Jupiter’s closest and third largest moon. It played a significant role in the first measurement of the speed of light, calculated by 17th-century Danish astronomer Ole Rømer. The most geologically active of Jupiter’s moons, Io has 30 active volcanoes that are probably energized by the tidal effects of Jupiter’s enormous mass. In 2001, the unmanned spacecraft Galileo came within 110 miles (180 km) of Io. What did its images reveal about Io? More… Discuss

tghis day in the yesteryear: Shoemaker-Levy 9 Comet Collides with Jupiter (1994)

Shoemaker-Levy 9 Comet Collides with Jupiter (1994)

In March 1993, astronomers Carolyn and Eugene Shoemaker and David Levy made the first observation of a comet orbiting a planet rather than the Sun. Sixteen months later, fragments of the comet collided with Jupiter’s southern hemisphere, providing the first direct observation of the collision of two solar system objects. The impact left prominent scars that some said were more easily visible than the planet’s Great Red Spot. How did the event highlight Jupiter’s role as “cosmic vacuum cleaner“? More… Discuss

today’s birthday: John Jacob Astor (1864)

John Jacob Astor (1864)

Astor was a financier and inventor. A man of many talents, he made a fortune in real estate, built the Astoria Hotel, invented a bicycle brake and a turbine engine, and wrote the science-fiction novel A Journey in Other Worlds about life on the planets Saturn and Jupiter. His second marriage to the much younger Madeleine Talmage Force caused a scandal, and the two took an extended honeymoon abroad to wait out the controversy. On their return trip, Astor was killed in what disaster? More… Discuss

this day in history: Pioneer 10 – First Craft to Leave Solar System, Perhaps (1983)

Pioneer 10: First Craft to Leave Solar System, Perhaps (1983)

Launched in 1972, Pioneer 10 was the first spacecraft to travel through the asteroid belt between Mars and Jupiter and to make up-close observations of Jupiter, capturing images that were later sent back to Earth. It passed the orbit of Neptune in 1983 and became by some definitions the first artificial object to leave our solar system. By February 1998, the probe was over 7.5 billion miles from Earth but lost its title as the most distant man-made object to what craft? More… Discuss


First Ringed Asteroid Identified

An asteroid orbiting the Sun between Saturn and Uranus has become the first asteroid identified as having rings. Until now, this feature had only been observed around the four gas giants, Saturn, Jupiter, Uranus, and Neptune. The 154-mile (248-km) asteroid, Chariklo, appears to have two distinct rings—one 4.3 miles (7 km) wide and the other 1.9 miles (3 km) wide—separated by a gap of about 5.6 miles (9 km). Given the rings’ crisp edges, astronomers suspect that Chariklo also has at least one moon, though none have yet been discovered. More… Discuss

The Great Red Spot: Jupiter’s Storm

The Great Red Spot (GRS) is a very large, high-pressure atmospheric feature on the planet Jupiter, characterized by anticyclonic winds circulating at a speed of about 248 mph (400 km/h). The storm has persisted on Jupiter’s surface for more than 300 years since first observed. The cause of its reddish color is unknown, and it tends to vary from brick-red to brownish. The GRS is not to be confused with another storm on Jupiter called “the Baby Red Spot,” which was initially what color? More… Discuss

Hail Yes!

Forget the Emerald City; on Saturn and Jupiter it is all about the diamonds. A team of US researchers is positing that lightning storms in the gas giants’ upper atmospheres turn methane into soot, which hardens into graphite and then diamond as it falls. Tons of diamondhailstones may rain down on the planets each year, and while most are likely about a centimeter in diameter, some could best be described as “diamondbergs.” Alas, these sparklers are not “forever.” As the diamonds reach certain depths, the pressure and temperature become so great that they likely melt into a liquid carbon sea. More… Discuss
