Astronomy Picture of the Day Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2024 February 9 When Roses Aren't Red Image Credit &Copyright: Tommy Lease(Denver Astronomical Society) Explanation: Not all roses are redof course,but they can still be very pretty.Likewise, the beautifulRosetteNebula and other star forming regions are often shown inastronomical images with a predominately red hue,in part because the dominant emission in the nebula isfrom hydrogen atoms.Hydrogen's strongest optical emission line, known as H-alpha,is in the red region of the spectrum.But the beauty of an emission nebula need not be appreciatedin red light alone.Other atoms in the nebula are also excited by energeticstarlight and produce narrow emission lines as well.In this close-up viewof the Rosette Nebula, narrowband images are mapped into broadbandcolors to show emission from Sulfur atoms in red, Hydrogen in green, andOxygen in blue.In fact, thescheme of mappingthese narrow atomic emission lines (SHO) into the broader colors (RGB) isadopted in manyHubble imagesof emission nebulae.This image spans about 50 light-years across the center of theRosette Nebula.The nebula lies some 3,000light-years awayin the constellation Monoceros.

APOD: 2024 January 19 - Jupiter over 2 Hours and 30 Minutes Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2024 January 19 Jupiter over 2 Hours and 30 Minutes Image Credit & License:Aurélien Genin Explanation: Jupiter, our Solar System's ruling gas giant, is also thefastest spinning planet,rotating once in less than 10 hours.The gas giant doesn't rotate like a solid body though.A day on Jupiteris about 9 hours and 56 minutes long at the poles,decreasing to 9 hours and 50 minutes near the equator.The giant planet's fast rotation createsstrong jet streams,separating its clouds into planet girdlingbands of dark belts and bright zones.You can easily follow Jupiter's rapid rotationin this sharp sequence of imagesfrom the night of January 15, all taken with a camera and smalltelescope outside of Paris, France.Located just south of the equator, the giant planet's giant stormsystem, also known asthe Great Red Spot,can be seen moving left to rightwith the planet's rotation.From lower left to upper right, the sequence spans about 2 hours and 30minutes.
