The Triangulum Emission Nebula - NGC 604Located 2.7 million light-years away in the constellation Triangulum lies the massive nebula known as NGC 604. Though such nebulae are common in galaxies, this one is particularly large, nearly 1,500 light-years across, and it dominates a portion of galaxy M33’s spiral arm. Nebula NGC 604 is also an area of intense star formation. At the heart of the nebula there are over 200 hot stars, most are more massive than our Sun with the largest being up...


Sword Of Orion: Orion constellation is known for 3 stars in short straight row called Orion’s Belt. A curved line of stars hangs from the three BELT stars; they're called Orion’s Sword as if a weapon with armor. The Orion Nebula is about midway down in the Sword of Orion, aka M42, a stellar nursery where new stars are being born. #DdO:) - - UNIVERSE LIGHTS.

If you could travel at 99.9% the speed of light, how long would it take you to get to the Moon? Mars? The nearest star? Hop aboard our interstellar starship and find out!


Stars ~ Stars form in the densest regions of the interstellar medium, or ISM, called molecular clouds. The ISM is the name given to the gas and dust that exists between the stars within a galaxy. It is 99% gas and 1% dust, by mass. Molecular clouds are perfect star-forming regions because the combination of these atoms into molecules is much more likely in very dense regions.


Stars form within nebula NGC 2170, which lies in the constellation of Monoceros (The Unicorn). A dark nebula, such as this one, provides raw material for the star formation going on inside them. The newly formed, massive blue stars seen here continue to push away traces of the dust that previously hid them from view. The material that remains will eventually disperse in the interstellar medium. [See more photos here.]

The strange symmetrically round nebula is the outcome of the prodigious energy output and fierce stellar winds of an unusually powerful star known as a Wolf-Rayet Star. The peculiar shape of the Bubble nebula marks the leading edge of the Wolf-Rayet wind front as it plows into the denser stationary material of the interstellar medium.


The Voyager spacecraft discovered a sea of magnetic bubbles frothing up out where the solar system meets the interstellar medium

This is Hebes Chasm on Mars. It forms a giant trough nearly 4.97 miles (8 km) deep, of Valles Marinera, the largest canyon system in the solar system. Taken with the High Resolution Stereo Camera on Mars Express.


NASA's Voyager 1 and 2 probes launched in 1977 to visit the outer planets of the solar system. After 35 years in space, the twin probes are approaching the edge of our solar system.
