LL Ori and the Orion Nebula  Image Credit: NASA, ESA, and The Hubble Heritage TeamExplanation: Stars can make waves in the Orion Nebula's sea of gas and dust. This esthetic close-up of cosmic clouds and stellar winds features LL Orionis, interacting with the Orion Nebula flow. Adrift in Orion's stellar nursery and still in its formative years, variable star LL Orionis produces a wind more energetic than the

Explanation: Could this close-by asteroid ever hit the Earth? Eventually yes -- but probably not for a very long time, even though the asteroid is expected to pass inside the orbit of the Moon next century. However, to better understand the nature and orbit of all near-Earth asteroids, NASA sent the robotic Origins, Spectral Interpretation, Resource Identification,

Astronaut Exploring: An Apollo 15 Panorama  Image Credit & Copyright: NASA, USGS, Apollo 15 Crew Explanation: What would it be like to explore the Moon? NASA's Apollo missions gave humans just this chance in the late 1960s and early 1970s. In particular, the Apollo 15 mission was dedicated to better understanding the surface of the Moon by exploring mountains, valleys, maria, and highlands. Astronauts David Scott and

Explanation: Many spiral galaxies have bars across their centers. Even our own Milky Way Galaxy is thought to have a modest central bar. Prominently barred spiral galaxy NGC 1672, featured here, was captured in spectacular detail in an image taken by the orbiting Hubble Space Telescope. Visible are dark filamentary dust lanes, young clusters of bright blue stars, red emission nebulas of glowing

Mars in the Loop  Image Credit & Copyright: Tunc Tezel (TWAN)Explanation: This composite of images spaced some 5 to 9 days apart, from late April (bottom right) through November 5 (top left), traces the retrograde motion of ruddy-colored Mars through planet Earth's night sky. To connect the dots and dates in this 2018 Mars retrograde loop, just slide your cursor over

A Lecture I attended a last year! Found the video by the Geological Society of London! Copied Video's Description: Why Earth developed into the crucible of life, and Venus into a hostile wasteland https://www.youtube.com/watch?v=o5FrCUQrFjs The present-day differences in the expression and intensity of volcanism on the planets of the inner solar system serves a testament to the

Title Hubble's 28th birthday picture: The Lagoon Nebula Released 19/04/2018 4:00 pm Copyright NASA, ESA, STScI, CC BY 4.0 To celebrate its 28th anniversary in space the NASA/ESA Hubble Space Telescope took this amazing and colourful image of the Lagoon Nebula. The whole nebula, about 4000 light-years away, is an incredible 55 light-years wide and 20 light-years tall. This image

Dove (http://www.flickr.com/photos/pldove/) Explanation: An unusual type of solar eclipse occurred in 2012. Usually, it is the Earth's Moon that eclipses the Sun. That year, most unusually, the planet Venus took a turn. Like a solar
