L2 the Second Lagrangian

L2 is one million miles from the Earth and 94 million miles from the Sun and is a resting place for smaller bodies (such as space telescopes) due to gravitational give and take.

In celestial mechanics, the Lagrangian points (/ləˈɡrɑːndʒiən/; also Lagrange points, L-points, or libration points) are positions in an orbital configuration of two large bodies, wherein a small object, affected only by the gravitational forces from the two larger objects, will maintain its position relative to them.

Abell 2142 - most massive object in the Universe?

Image
Abell 2142, or A2142 , is a huge, X-ray luminous galaxy cluster in the constellation Corona Borealis . It is the result of a still ongoing merger between two galaxy clusters. The combined cluster is six million light years across, contains hundreds of galaxies and enough gas to make a thousand more. It is "one of the most massive objects in the universe."

Schiaparelli (SkiAppUhRelEE)

Image
Schiaparelli EDM lander [skjapaˈɾɛlːi] was the Entry, Descent and Landing Demonstrator Module (EDM) of the ExoMars programme—a joint mission of the European Space Agency (ESA) and the Russian space agency Roscosmos . [4] It was built in Italy and was intended to test technology for future soft landings on the surface of Mars . [5] It also had a limited but focused science payload that would have measured atmospheric electricity on Mars and local meteorological conditions.

Solar System

Image
The Solar System [a] is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. [b] Of those objects that orbit the Sun directly, the largest eight are the planets , [c] with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies . Of the objects that orbit the Sun indirectly, the moons , two are larger than the smallest planet, Mercury . [d] The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud . The vast majority of the system's mass is in the Sun, with most of the remaining mass contained in Jupiter . The four smaller inner planets, Mercury , Venus , Earth and Mars , are terrestrial planets , being primarily composed of rock and metal. The four outer planets are giant planets , being substantially more massive than the terrestrials. The two largest, Jupiter and Saturn , are gas giants , being compose...
