Thirty years after the first exoplanets were discovered, hundreds of additional exoplanets have been identified within the “habitable zone,” a place where liquid water and maybe even life may exist. The MIT Press Reader asks, could a self-sustaining starship carry humans to distant worlds? https://flip.it/0q093h

The International Max Planck Research School for Solar System Science becomes a permanent institution in Göttingen and Braunschweig

The Solar System School, the joint graduate school of the Max Planck Institute for Solar System Research, the University of Göttingen, and the Technical University of Braunschweig, is now a permanent fixture in doctoral training in Göttingen and Braunschweig. The Max Planck Society will continue the International Max Planck Research School for Solar System Science at the University of Göttingen and at TU Braunschweig for an indefinite period. The IMPRS doctoral program offers students from all over the world the opportunity to obtain a doctorate in the field of solar system research... https://www.mps.mpg.de/bright-future-for-solar-system-school

A collage of four photographs showing doctoral researchers in various work settings. From left to right and from top to bottom, the four pictures show: Two young women, one sitting and one standing, in front of computer screens on a desk in an office, looking at the screens and pointing. A young man in a light mint green T-Shirt in a lab environment, standing with his back to the viewer, his body facing machinery but his head turned back over his right shoulder to face the viewer. A person in white clean room attire including gloves and a hair net bent over a lab bench with equipment sitting on it, their hand stretched out to the piece's end that's oriented towards the viewer. Bottom right, a control room with desks and monitors as well as a large screen on the wall, operated by two young researchers sitting at the desks and focusing on the monitors and screens.

#OTD in 1892.

Amalthea becomes the last moon to be discovered without the use of photography. It was discovered by Edward Emerson Barnard and named it after Amalthea, fost-mother of Zeus.

Barnard used the 91 cm refractor telescope at Lick Observatory and was the first new satellite of Jupiter since Galileo Galilei's discovery of the Galilean satellites in 1610.

#OTD in 1789.

William Herschel discovers a new moon of Saturn: Enceladus, but little was known about it until the two Voyager spacecrafts, Voyager 1 and Voyager 2, flew by Saturn in 1980 and 1981. Like many satellites of Saturn discovered prior to the Space Age, Enceladus was first observed during a Saturnian equinox, when Earth is within the ring plane.

https://en.wikipedia.org/wiki/Enceladus

#astronomy #solarsystem

This color Voyager 2 image mosaic shows the water-ice-covered surface of Enceladus, one of Saturn's icy moons. Enceladus' diameter of just 500 km would fit across the state of Arizona, yet despite its small size Enceladus exhibits one of the most interesting surfaces of all the icy satellites. Enceladus reflects about 90% of the incident sunlight (about like fresh-fallen snow), placing it among the most reflective objects in the Solar System. Several geologic terrains have superposed crater densities that span a factor of at least 500, thereby indicating huge differences in the ages of these terrains. It is possible that the high reflectivity of Enceladus' surface results from continuous deposition of icy particles from Saturn's E-ring, which in fact may originate from icy volcanoes on Enceladus' surface. Some terrains are dominated by sinuous mountain ridges from 1 to 2 km high (3300 to 6600 feet), whereas other terrains are scarred by linear cracks, some of which show evidence for possible sideways fault motion such as that of California's infamous San Andreas fault. Some terrains appear to have formed by separation of icy plates along cracks, and other terrains are exceedingly smooth at the resolution of this image. The implication carried by Enceladus' surface is that this tiny ice ball has been geologically active and perhaps partially liquid in its interior for much of its history.
