Asteroid 16 Psyche Might Not be a Solid Chunk of Metal After All, but Another Rubble Pile

Asteroid 16 Psyche, often sensationally dubbed the 10,000 quadrillion dollar asteroid due to its composition of valuable metals, may not be entirely what it seems.  A new paper out of the University of Arizona suggests that the asteroid is possibly more porous, and less metallic, than previous studies indicated. It still certainly has a mostly …

What’s the Connection Between the Chemistry of a Star and the Formation of its Planets?

Scientists seem to have come up with a new parlor game – how many ways can we potentially detect exoplanets?  The two most common methods, the transit method and the Doppler method, each have their own problems.  Alternative methods are starting to sprout up, and a new one was recently proposed by Jacob Nibauer, an …

ESA is Joining NASA With Their own Mission to Venus

It's an exciting time to be a Venus watcher.  Our sister planet, which has been the target of only one mission since the 1980s, is now the focus of not one, not two, but three missions from NASA and ESA.  Combined, they promise to give the closest look ever at the Morning Star, and some …

What Mission Could Detect Oceans at Uranus’ Moons?

Exploration of ocean worlds has become a hot topic of late, primarily due to their role as a potential harbor for alien life.  Moons that have confirmed subsurface oceans garner much of the attention, such as Enceladus and Europa.  But they may not be the only ones.  Uranus' larger moons – Miranda, Ariel, and Umbriel …
