By starlight this eerie visage shines in the dark, a crooked profile evoking its popular name, the Witch Head Nebula. In fact, this entrancing telescopic portrait gives the impression the witch has fixed her gaze on Orion's bright supergiant star Rigel. Spanning over 50 light-years, the dusty cosmic cloud strongly reflects nearby Rigel's blue light, giving it the characteristic color of a reflection nebula.
"Planet X" might actually exist — and so might "Planet Y."
At least two planets larger than Earth likely lurk in the dark depths of space far beyond Pluto, just waiting to be discovered, a new analysis of the orbits of "extreme trans-Neptunian objects" (ETNOs) suggests.
Researchers studied 13 ETNOs — frigid bodies such as the dwarf planet Sedna that cruise around the sun at great distances in elliptical paths.
Van Truong, 19, the creative student who made this collection of notes said,
"I knew if I had to read through a packet of notes, I'd fall asleep," Truong said. "I don't know if I would've lasted through three hours just going through notes."
Truong said she chose to recreate "Starry Night" because of its composition. Unlike a portrait of a person, which she thought would look disjointed if made out of individual lines of biology notes, words and sentences could look like Van Gogh's brush strokes.
