Pluto (bottom Image) With Various Other Non-planets.

“The more I look at Earth, and certain parts of Earth, the more I feel like an environmentalist. It’s just a blanket of pollution in certain areas. We can fix that if we put our minds to it.“

-Astronaut Scott Kelly, whose one year long mission in space ended today (01/03/2016)

I love how stars are billions of miles apart and we’re like “that’s a soup ladle”.

A Montage of the Carina Nebula

The Carina Nebula (known by astronomers as NGC 3372) is sometimes called the Great Nebula in Carina or the Grand Nebula. These images taken by the Hubble space telescope show the magnificent structure within the Carina Nebula. These images contain regions of dense star formation, interstellar winds, massive particle clouds and much more. Many of these structures are hundreds of light-years across and make the size of our solar system look pathetic in comparison. The Carine Nebula is about 10,000 light-years away from earth and is located in the constellation Carina.

It's amazing how these galaxies, that are so unfathomably huge to us, are actually really fragile and delicate in the scheme of things

Top 10 Bizarre Galaxy Pairs From Hubble

“The Arp catalog illustrates galaxies in many different stages of a collision:

* prior to their first close pass, * in the collision process, * subsequent to an interaction but before merging, * and in the final merger stages.

Unlike ellipticals, spirals are easily disturbed, often becoming destroyed entirely by such an interaction.”

When you take a glimpse into the deep Universe, beyond the gas, dust, stars and planets of our own galaxy, you enter the realm of the galaxies. In general, they come in two types: the spirals, with neat, orderly arms, and the ellipticals, with a symmetric, bulging shape. But for everything that exists in the Universe a particular way in general, there are exceptions. In the 1960s, astronomer Halton Arp became fascinated with these exceptions, creating a catalog of 338 examples: the Atlas of Peculiar Galaxies. We now know that most of these are galaxy pairs or triplets in the process of major mergers, displaying features such as tidal disruption, stellar bridges, starbursts and occasionally a rare, ring shape.

More cool space words:

Apastron: the point where two binary stars are farthest apart.

Azimuth: distance of an object in angular.

Bolide: an especially bright meteor, especially one that explodes in the atmosphere (also called fireballs!).

Catena: a chain or series of craters.

Ejecta: material that is strewn about a crater by an impact, usually a meteorite or other similar object.

Ephemeris: a table that lists the positions of the sun, moon, and planets by date.

Heliosphere: the magnetic bubble of space that contains our solar system, solar wind, and the entire solar magnetic field. It is so large it goes beyond pluto's orbit.

Meridian: an imaginary circle that goes through the north and south poles, and the zenith and nadir of a location.

Nadir: the point in the sky directly underneath you.

Nova: when a dying star suddenly flares in brightness. The star becomes thousands of times its original luminosity.

Prominence: an explosion on the surface of the Sun.

Singularity: the impossibly small space in the center of a black hole where density and gravity are infinite, and space-time curves infinitely.

Spicules: a jet of gas ejected from the sun's atmosphere that resembles grass.

Supernova: one of the most powerful forces in the universe. When a star uses up all of its fuel it ends its life in a spectacular and devastating explosion.

Terminator: line on a planetary body that separates the light side from the dark side.

Umbra: the darkest part of a shadow.

Zenith: the point in the sky directly overhead.

Zodiac: an imaginary belt across the sky that the sun, moon, and planets are always in. The zodiac is made up of 12 constellations.
