It’s that time of year again, time for one of my favorite holiday traditions: the 11th annual Hubble Space Telescope Advent Calendar. Every day until Tuesday, December 25, this page will present one new incredible image of our universe from NASA’s Hubble telescope. Be sure to bookmark this calendar and come back every day until the 25th, or follow on Twitter (@TheAtlPhoto), Facebook, or Tumblr for daily updates. I hope you enjoy these amazing and awe-inspiring images and the efforts of the science teams who have brought them to Earth. As I do every year, I want to say again how fortunate I feel to have been able to share photo stories with you all year, and how much fun I have putting this calendar together every December. Wishing you all a merry Christmas, happy holidays, and peace on Earth.

Miguel Claro is a professional photographer, author and science communicator based in Lisbon, Portugal, who creates spectacular images of the night sky. As a European Southern Observatory Photo Ambassador and member of The World At Night and the official astrophotographer of the Dark Sky Alqueva Reserve, he specializes in astronomical “Skyscapes” that connect both Earth and night sky. Join Miguel here as he takes us through his photograph “The Colourful Spiral Galaxy of Andromeda.”

Around the same time that the first human ancestors of the genus Homo roamed the Earth, light from the Milky Way’s closest neighboring galaxy began its 2.5 million-year trek to our planet, creating the image we see today.

Homo, the genus that includes modern humans, is estimated to be between 1.5 and 2.5 million years old. Meanwhile, the Andromeda galaxy (M31) is 2.5 million light-years away from Earth. In the amount of time it took for that light to reach us, humans have evolved from the stone tool-wielding Homo habilis up to the point where we have the necessary technology to construct powerful telescopes, giving us the capability to observe, study, photograph and understand the wonders of the vast universe.

NASA’s Lunar Reconnaissance Orbiter captured this stunning image of a lunar crater on Nov. 3.

I hope you’re not all partied out after the InSight lander’s successful touchdown on Mars this week, because there’s another big spaceflight event just around the corner.

NASA’s OSIRIS-REx probe will officially arrive at the near-Earth asteroid Bennu at about 12 p.m. EST (1700 GMT) on Monday (Dec. 3), ending a 27-month deep-space chase. NASA will mark the occasion with a special webcast event from 11:45 a.m. to 12:15 p.m. EST (1645 to 1715 GMT), which you can watch live here at Space.com, courtesy of NASA TV.

The space agency will also air an “arrival preview program” at 11:15 a.m. EST (1615 GMT). You can catch that here at Space.com as well. [OSIRIS-REx: NASA’s Asteroid Sample-Return Mission in Pictures].

Founder Richard Branson is “pretty confident” it’ll happen.

During my first full day here, I broke my first record by generating more electrical power than any previous robot on the surface of Mars. I’m in a sandy area with few rocks, soaking up the Sun. 🌞 More about where I landed: http://go.nasa.gov/2RvGiMl&h=AT18X8EjCOTXbtitHthnNUzrg5IiHWx…p1W1lBoVnw

Chang’e-4 mission will test plant growth on the Moon, and listen for radio emissions normally blocked by Earth’s atmosphere. Instruments on board the lander will carry out the first radio astronomy observations from the Moon’s far surface.
