On December 16, 1992, eight days after its final encounter with Earth, NASA’s Galileo spacecraft looked back and captured this remarkable view of Earth and the moon.Continue reading A 1992 Family Portrait of Earth and the Moon
As of 2019, only five space probes are leaving the solar system: Pioneer 10, Pioneer 11, Voyager 1, Voyager 2 and New Horizons. The Voyagers already left the solar system and entered the interstellar space (Voyager 1 on August 25, 2012, and Voyager 2 on November 5, 2018. The others also will leave the heliosphere Notes 1 and reach the interstellar space in a few years.
All of these spacecraft are launched by NASA.Continue reading Five space probes leaving the solar system (for now)
NASA Goddard Planetary Scientist James O’ Donoghue created a nice animation showing the sidereal days and axial tilts of the solar system planets.Continue reading The sidereal days and axial tilts of the Planets
Previously I posted articles titled “If The Moon Were Only 1 Pixel – A Tediously Accurate Map Of The Solar System” and “A Scale Model Of Solar System Drawn In The Desert And The Result Is Stunning”. Since the human brain cannot deal with the really large numbers, these articles provide amazing ways to understand how big actually our Solar System is.
Now, in his YouTube channel, The Science Asylum, physicist Nick Lucid provides yet another scale model of the solar system. A very nice video conceptualizing how mind-bogglingly big our solar system (and space) is.Continue reading Watch: Yet Another Scale Model of the Solar System
This size comparison of the Sun and the planets in our solar system is going around frequently, but it’s still amazing to see it. Created by the San Francisco-based artist Roberto Ziche,Continue reading Size comparison of the Sun and the planets
From blob-like jellyfish to rock-like lichens, our planet teems with such diversity of life that it is difficult to recognise some organisms as even being alive. That complexity hints at the challenge of searching for life as we don’t know it – the alien biology that might have taken hold on other planets, where conditions could be unlike anything we’ve seen before. ‘The Universe is a really big place. Chances are, if we can imagine it, it’s probably out there on a planet somewhere,’ said Morgan Cable, an astrochemist at the Jet Propulsion Laboratory in Pasadena, California. ‘The question is, will we be able to find it?’Continue reading To find aliens, we must think of life as we don’t know it
What would it be like to stand on the surface of another planet? “We The Curious” channel has teamed up with a group of astrophysicists to create a scientifically accurate virtual reality tour of six planets discovered outside our solar system. The fruit of this collaboration is the video below, in 4K Ultra-HD and 360-degree. Narrated and produced by Ross Exton.
