[/caption] When you look at an image of Mercury, it looks like a dry, airless world. But you might be surprised to know that Mercury does have an atmosphere. Not the kind of atmosphere that we have here on Earth, or even the thin atmosphere that surrounds Mars. But Mercury’s atmosphere is currently being studied …
[/caption] NASA’s Dawn mission is getting a whopping boost in science observing time at the closest orbit around Asteroid Vesta as the probe passes the midway point of its 1 year long survey of the colossal space rock. And the team informs Universe Today that the data so far have surpassed all expectations and they …

[/caption] The more we explore our solar system, the more we find things in common. Jupiter’s frigid moon – Europa – is about the size of our satellite and – like Earth – home to some very hostile environments. Underneath what is surmised to be an icy crust a few miles deep, Europa may possess …
[/caption] Changing seasons in Mars’ northern hemisphere brings a change in the weather, and the clouds have rolled in to cover part of the polar surface in this intriguing image from the Mars Odyssey spacecraft. Mars Odyssey’s THEMIS visual imager (VIS) captured this image on Jan. 24, 2012, as it passed over the Red Planet’s …
[/caption] If you’ve always dreamed of being an astronaut here’s the next best thing, and the location couldn’t be more idyllic. Scientists from Cornell and the University of Hawaii are conducting a 120-day Mars exploration analog study in a simulated Mars habitat on the lava fields of the Big Island of Hawai’i. The study will …

In this edition, we talk about the non-discovery of faster-than-light neutrinos, the possibility of quakes on Mars, and explanation for the ridge on Iapetus, the 25th anniversary of SN1987A, and a steamy water world.
[/caption] NASA released a new interactive infographic that attempts to give a picture of future of human spaceflight activities and where NASA might be going. The new Space Launch system and the Orion MPCV figure prominently in going to future destinations such as the Moon, Mars, Near Earth Asteroids and even LaGrange Points. It would …

[/caption] As we learned in science class in school, the Earth has a molten interior (the outer core) deep beneath its mantle and crust. The temperatures and pressures are increasingly extreme, the farther down you go. The liquid magmas can “melt” into different types, a process referred to as pressure-induced liquid-liquid phase separation. Graphite can turn …

[/caption] NASA announced yesterday that it’s looking for new technology proposals using environmentally friendly fuels to launch payload. The space agency is hoping to move away from hydrazine, the fuel that currently launches anything that travels beyond the atmosphere from commercial satellites to private spaceflight and exploration probes. As a rocket propellant, hydrazine is great. …
[/caption] The giant Asteroid Vesta literally floats in space in a new high resolution 3-D image of the battered bodies Eastern Hemisphere taken by NASA’s Dawn Asteroid Orbiter. Haul out your red-cyan 3-D anaglyph glasses and lets go whirling around Vesta and sledding down mountains to greet the alien Snowman! The sights are fabulous ! …
