Have you ever wondered what sunsets on other worlds might look like?
Now you can find out, thanks to simulations created by Goddard scientist Geronimo Villanueva.
When sunlight interacts with molecules in a planet’s or moon’s atmosphere, it creates the kaleidoscope of colors you see in these simulations.

In its 10 years observing the Sun, our Solar Dynamics Observatory satellite has gathered over 425 million high-resolution images of our star.
This 10-year time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that shows the Sun’s outermost atmospheric layer — the corona. Compiling one photo every hour, the movie condenses a decade of the Sun into 61 minutes. The video shows the rise and fall in activity that occurs as part of the Sun’s 11-year solar cycle and notable events, like transiting planets and eruptions. The custom music, titled “Solar Observer,” was composed by musician Lars Leonhard.
Is the Sun an Oddball Star? A fascinating conversation with Kepler and TESS astronomer Travis Metcalfe, of the Space Science Institute in Boulder, Colo., about how our Sun stacks up against other sunlike stars in the galaxy. We cover the history of our solar system, where the Sun might have been born, and why the only intelligent life we know is around this lonely G-Dwarf star.
The star may be extremely young, but its ring of rock and dust is enormous. The size of just the shadow alone would be hundreds of times the size our entire solar system, according to NASA. Light would take more than a month to travel that distance.
By taking additional pictures using filters, the team was able to create a gorgeous, colored image of the star and its “bat shadow.”

Mankind has no choice but to colonise Mars if human beings are to have a future, physicist and science populariser Brian Cox has said. Currently a professor at Manchester University in the UK, Cox has found global fame as a presenter of documentaries, taking millions of viewers on virtual journeys through the galaxy.
INews.co.uk reports:
Professor Brian Cox has said humans will one day live on Mars and be the Martians of the future.
Before going to space, should we solve the problems here, on Earth?
Whenever we speak about human presence in space to a general audience, and quite often when we talk with specialists as well, we have to hear the Great Objection:” Before going to space, we have to solve our problems here, on the Earth”.
As soon as we reason about it we understand that the Objection is in fact a general dialectic scheme, which consists in changing the topic, pretending that the alternative is more important and urgent and so avoiding to reply to what the speaker has said. In short, it is a sort of quite-another-ism: “The problem is quite another, the cause is quite another…”.
No, you’re not dreaming! An asteroid full of gold may have been discovered. We’ll fill you in about this unprecedented discovery.
As astonishing as it may seem, NASA may have discovered an asteroid filled with gold. According to International Business Times, NASA discovered this asteroid, called Psyche 16, between Mars and Jupiter.
Reports are that this celestial body is mainly composed of solid metals, such as gold, platinum, nickel, and iron.
It is one of the most astonishing results of physics: when a complex system is left alone, it will return to its initial state with almost perfect precision. Gas particles, for example, chaotically swirling around in a container, will return almost exactly to their starting positions after some time. This “Poincaré Recurrence Theorem” is the foundation of modern chaos theory. For decades, scientists have investigated how this theorem can be applied to the world of quantum physics. Now, researchers at TU Wien (Vienna) have successfully demonstrated a kind of “Poincaré recurrence” in a multi-particle quantum system. The results have been published in the journal Science.
An Old Question, Revisited
At the end of the 19th century, the French scientist Henri Poincaré studied systems which cannot be fully analysed with perfect precision — for example solar systems consisting of many planets and asteroids, or gas particles, which keep bumping into each other. His surprising result: every state which is physically possible will be occupied by the system at some point — at least to a very good degree of approximation. If we just wait long enough, at some point all planets will form a straight line, just by coincidence. The gas particles in a box will create interesting patterns, or go back to the state in which they were when the experiment started.
