An asteroid recently made the second closest pass to Earth ever observed on October 1st. And astronomers only found it after it had already completed its closest approach. That offers another lesson in how difficult it is to find small objects coming close to our planet in the vast dark ocean of space.
As part of World Space Week, which is highlighting the theme of living in space, we look at one scientist's dream of gigantic space habitats.
By fitting its sunshield and solar panels, engineers have completed the construction of Plato, the European Space Agency’s mission to discover Earth-like exoplanets. Plato is on track for the final key tests to confirm that it is fit for launch.
Today, it's a scientific consensus that Mars was once a very different place, with a warmer, denser atmosphere and liquid water on its surface. This is evidenced by flow channels, delta fans, lakebeds, and many other features that form in the presence of flowing water here on Earth. Based on the way many of these channels feed into the Northern Lowlands on Mars, scientists speculate that this region was once home to an ocean that covered the northern hemisphere. According to new research from the University of Arkansas, there is a strong case for the existence of this ancient ocean.
What if our understanding of Uranus and Neptune’s compositions have been wrong, specifically regarding their classifications as “ice giants”? This is what a recent study accepted for publication in *Astronomy & Astrophysics* hopes to address as a team of researchers from the University of Zurich investigated the interior structures of Uranus and Neptune. This study has the potential to help scientists not only better understand the formation and evolution of Uranus and Neptune but could also provide key insights into Jupiter and Saturn, and gaseous exoplanets, too.
Blue Origin rolled the first stage of its powerful New Glenn rocket to the pad Wednesday (Oct. 8) for testing ahead of a planned launch of two NASA Mars probes.

Two decades of spacecraft images reveal more than 1,000 dust devils whipping across Mars at unexpected speeds, offering fresh insight into how wind and dust shape the Red Planet.
The Big Bang essentially created two elements: hydrogen and helium. It also produced tiny traces of lithium and a few other light isotopes, but in the beginning there was hydrogen and helium. All the other, heavier elements formed later, either in the cores of stars, through stellar collisions, or other astrophysical processes. Even now hydrogen and helium make up so much of the material world that astronomers refer to all other elements as metals. Dust in the wind, you might say.
This newly discovered comet could soon glow bright enough for the naked eye as it sweeps through October's morning and evening skies.
