Scientists Improve Brown Dwarf Weather Forecasts

Spitzer Space Telescope -

Dim objects called brown dwarfs, less massive than the Sun but more massive than Jupiter, have powerful winds and clouds -- specifically, hot patchy clouds made of iron droplets and silicate dust. Scientists recently realized these giant clouds can move and thicken or thin surprisingly rapidly, in less than an Earth day, but did not understand why.

The Art of Exoplanets

How do you visualize distant worlds that you can't see? IPAC's Robert Hurt and Tim Pyle are featured in a new video produced by JPL that highlights how they use scientific data to imagine exoplanets and other astrophysical phenomena.

5000 Days in the Life of an Astronomy Robot

Spitzer Space Telescope -

May 3rd, 2017 marks the 5,000th day of NASA's Spitzer Space Telescope mission. This video gives us a detailed look at six of these days, showing how an automated observatory like Spitzer, which is effectively an astronomy robot, spends its time. It’s overall mission design allows for an unprecedented degree of efficiency, allowing it to study the full range of astronomical phenomena including nearby objects in the solar system, stars in our galaxy, and galaxies out to the edge of the observable universe.
