Shared images NASA will present ghostly wonders of space this week just before the most unearthly day of the year: Halloween.
The agency posted two photos on Twitter: one of the celestial phenomena that look like a galactic ghost and one of the sun resembling a burning lantern.
Let our messages go to your inbox. The most important news and stories were provided on weekdays.
"Spectral phenomenon" as described by NASA on Tuesday on Twitter, it's actually a photo of two colliding galaxies taken by the Hubble Space Telescope in June.
"Each" eye "is the bright core of the galaxy, one of which hit the other," NASA explained on its website. "The face contour is a ring of young blue stars. Other clusters of new stars form the nose and mouth. "
The frontal collision will give the galaxies a ring structure for about 100 million years, which according to NASA is a rare cosmic circumstance. Ultimately, in about 1 or 2 billion years, the two galaxies will completely merge.
But in the meantime, don't let the ghostly picture haunt your dreams. The galactic ghoul is about 704 million light years away from Earth.
As for the photo reminiscent of a menacing pumpkin head, only matching the character from Sleepy Hollow, it was originally taken in 2014 by Solar Dynamics Observatory and again shared on Twitter on Monday. NASA said that the active regions of the Sun are highlighted as markers of an intense and complex set of magnetic fields floating in the Sun's atmosphere.
"This image combines two sets of wavelengths at 171 and 193 angstroms, usually colored in gold and yellow, to create a particularly Halloween-like look," NASA said on his site.
