Breaking News: Haumea dwarf planet has a ring to it: study - News Paper-News of the United States was founded in 1933 by David Lawrence (1888-1973), which also started the World Report in 1946. The two magazines are covering national and international news separately, but Lawrence combines them into news reports of U.S. in World and 1948 [1] and Later sold the magazine to its employees. Historically, this magazine tends to be a bit more conservative than the two main competitors, Time and Newsweek, and focus more on the story of economic, health, and education. It's also distancing news, entertainment and sports celebrities. [2] an important milestone in the history of the beginning of the magazine is including the introduction of the "Washington Whispers" column in 1934 and the column "News You Can Use" in 1952. [3] [4] in 1958, the circulation of the weekly magazine passed one million and two million in 1973. (wikipedia) Breaking News: Haumea dwarf planet has a ring to it: study - News Paper
Move over Saturn! Scientists have found a ring around an unassuming mini-planet in our Solar System to debunk the theory that only giant planets can be so adorned.
Artistic concept of Haumea and its ring system with correct proportions for the main body and the ring. The ring is located at a distance of 2287 km with respect to the center of the ellipsoidal main body and it is darker than the surface of Haumea. It was discovered by means of multiple telescopic observations of a stellar occultation in Europe on January 21st, 2017. This and other findings on Haumea are reported in a Nature paper by Ortiz et al. (2017) entitled “The size, shape, density and ring of the dwarf planet Haumea from a stellar occultation” [Credit: IAA-CSIC/UHU]
The planet, dubbed Haumea, orbits the Sun far beyond Neptune—the eighth and furthest recognised "full" planet in our star system since Pluto was downgraded to dwarf status in 2006.
About eight billion kilometres (five billion miles) from the Sun, Haumea spins rapidly on its own axis, and has a flattened, cigar-like shape.
It takes 285 years to circle the Sun.
Named after the Hawaiian goddess of childbirth, it is among a handful of known dwarf planets beyond the orbit of Neptune, which with the other so-called giant planets—Saturn, Uranus and Jupiter—all have rings.
"Our discovery proves that there is a lot more diversity and imagination in our solar system than we had thought," study co-author Bruno Sicardy of the Paris Observatory told AFP.
A ring system had previously been discovered around a centaur dubbed Chariklo. Centaurs, which have unstable orbits, are considered large comets, not planets, which means this is the first observation of a ring around a dwarf planet.
The new discovery came when Sicardy and a team predicted that Haumea would cross in front of a specific star, from Earth's perspective, on January 21 this year.
They trained 12 telescopes at 10 different laboratories on the spot, and were able to measure many of the physical characteristics of the little-known planet discovered in 2004.
Scientists can infer much about a planet's density and size by how much light it blocks out as it moves in front of a star.
In Haumea's case, they found it sported a dense, Saturn-like ring some 70 kilometres wide, made of frozen particles.
