Jupiter and the Asteroids
Most asteroids orbit peacefully between Mars and Jupiter. However, many asteroids have orbits that have been determined by Jupiter’s massive gravity.

The Trojans (green) share Jupiter’s orbit, and are always about 60 degrees ahead of, or behind, Jupiter. These are the Lagrangian points L4 and L5. At these points, the gravity of Jupiter and the Sun balance out, forming a sort of gravity island. L4 and L5 are stable, meaning that an asteroid that strays from the precise balance point will tend to return to that point.

The Hildas (red) are in a 3:2 resonance with Jupiter – they complete 3 orbits for every 2 orbits of Jupiter.
Their orbits are eccentric, and arranged so that when they overtake Jupiter, they are closest to the Sun (and therefore furthest from Jupiter). The helps to prevent Jupiter’s gravity from disrupting their orbits.
The effect is that Jupiter “herds” them around the Sun, while they stay in a roughly triangular shape.

Near Earth Asteroids (not shown) have orbits that bring them close to the Earth. Almost all of these have been tossed out of the asteroid belt because of gravity interactions with Jupiter. One such asteroid caused the dinosaurs to have a very bad day.

"Fundación de la belleza."
Están allí, pintadas en las paredes y en los techos de las cavernas.
Estas figuras, bisontes, alces, osos, caballos, águilas, mujeres,
hombres, no tienen edad. Han nacido hace miles y miles de años,
pero nacen de nuevo cada vez que alguien las mira.
¿Cómo pudieron ellos, nuestros remotos abuelos, pintar de tan
delicada manera? ¿Cómo pudieron ellos, esos brutos que a mano
limpia peleaban contra las bestias, crear figuras tan llenas de gra-
cia? ¿Cómo pudieron ellos dibujar esas líneas volanderas que es-
capan de la roca y se van al aire? ¿Cómo pudieron ellos…?
¿O eran ellas?

"New Exoplanet-hunting Telescopes on Paranal"
(5 min, Jan 2015) The Next-Generation Transit Survey (NGTS) will search for transiting exoplanets — planets that pass in front of their parent star and hence produce a slight dimming of the star’s light that can be detected by sensitive instruments. The telescopes will focus on discovering Neptune-sized and smaller planets, with diameters between two and eight times that of Earth. NGTS is designed to operate in a robotic mode and it will continuously monitor the brightness of hundreds of thousands of comparatively bright stars in the southern skies.

The NGTS discoveries, and follow-up observations by telescopes on the ground and in space, will be important steps in our quest to study the atmospheres and composition of small, Earth-like planets.

TOUCHDOWN! ROSETTA'S #PHILAE PROBE LANDS ON COMET

> Think of the science that was incorporated into this mission, proving that many nations, #argentina, #spain and #germany, can work together to further space exploration.

After a tense wait during the seven-hour descent to the surface of Comet 67P/Churyumov–Gerasimenko, the signal confirming the successful touchdown arrived on Earth at 16:03 GMT (17:03 CET).
The confirmation was relayed via the #Rosetta orbiter to Earth and picked up simultaneously by ESA's ground station in Malargüe,
Argentina and NASA's station in Madrid, Spain.

The signal was immediately confirmed at ESA's Space Operations Centre, #ESOC, in #Darmstadt, and DLR's Lander Control Centre in #Cologne, both in Germany.

The first data from the lander's instruments were transmitted to the Philae Science, Operations and Navigation Centre at France's #CNES space agency in Toulouse.

"Our ambitious #Rosetta mission has secured a place in the history books: not only is it the first to rendezvous with and orbit a comet, but it is now also the first to deliver a lander to a comet's surface," noted Jean-Jacques Dordain, ESA's Director General.

 "With Rosetta we are opening a door to the origin of planet Earth and fostering a better understanding of our future. #ESA and its Rosetta mission partners have achieved something extraordinary today."

"After more than 10 years travelling through space, we're now making the best ever scientific analysis of one of the oldest remnants of our Solar System," said Alvaro Giménez, ESA's Director of Science and Robotic Exploration. "

Thank you to +Marta Rauch for first making me aware of this historic mission.
