Scientists have just gotten the best-ever look at Mars — though they still haven’t spotted any aliens.
Nevertheless, the incredible new Mars images (see more below) reveal some of the planet’s most exciting features like never before.
Turns out your trip might have been in the name of science after all. Researchers monitoring the neural activity of participants in a new study recently produced the first images of the…
A new report says we’re closer to finally tracking down the elusive Planet 9.
The new study, published by Christoph Mordasini and Esther Linder in Astronomy & Astrophysics, suggests that Planet 9 is an ice giant, smaller than Uranus and Neptune. Mordasini and Linder also predicted that if the planet is the size they believe it is, several more objects should be forced into orbit around it. So far, they have located five objects that fit these conditions.
That’s not to say we’ll be able to see it, though. The planet’s hypothetical orbit is so far from the sun that most of its energy would be produced by its own core. This distance from the sun makes it difficult for traditional telescopes to pick up any light that it might reflect. Thus, Linder and Mordasini don’t believe existing telescopes are powerful enough to detect the planet.
But catching a glimpse of this mysterious planet is not out of the question. The Large Synoptic Survey Telescope, currently under construction in Chile, is “designed to take a ten year survey of the Universe” using a 3200-megapixel camera which will most likely be able to spot Planet 9 — if it exists.
Mordasini and Linder’s work builds on the research of astronomers at Caltech, who essentially showed that Planet 9 isn’t just a myth. While modeling orbits of several objects in the Kuiper Belt, they realized that these orbits would not take their shapes without the effects of gravity from an unknown planet — which they believe is probably ten times more massive than Earth, and located out past Neptune in the Kuiper Belt. In other words, it was Planet 9 that shaped these orbits.
On April 13, 1970, an oxygen tank exploded aboard Apollo 13, forcing American astronauts Jim Lovell, Jack Swigert, and Fred Haise to act quickly in order to save the spacecraft — as well as their own lives. The explosion forced the crew to abandon their mission — to reach the moon — but the crew’s heroics saved the craft, and saved NASA from another tragedy just three years after the Apollo 1 disaster.
Forty-six years later, we look beyond those two accidents and survey, via photographs from the missions, some of the most important achievements in the history of the Apollo program:
