How Dark Matter Could Be Measured in the Solar System
Dark matter in our backyard
Here on Earth, our planet’s gravity keeps us from flying out of our chairs, and the Sun’s gravity keeps our planet orbiting on a 365-day schedule. But the farther from the Sun a spacecraft flies, the less it feels the Sun’s gravity, and the more it feels a different source of gravity: that of the matter from the…

Happy 15th birthday, Spitzer!
The Spitzer Space Telescope is an infrared space telescope launched on August 25, 2003, the last in NASA’s Great Observatories Program.
Spitzer uses three instruments to get some of the stunning photos we see today: the Infrared Array Camera (IRAC), an imaging camera, designed to detect light at near and mid-infrared wavelengths; the Infrared Spectrograph (IRS), which provides both high and low resolution spectroscopy; the Multiband Imaging Photometer (MIPS), another imaging camera that detects light in the far infrared. Lastly, the Cryostat: which keeps Spitzer cold, allowing the scope to look for faint radiation from objects in our universe.
Given a 5 year mission, the Spitzer Space Telescope has much surpassed that, most recently used to discover 5 of 7 planets in the TRAPPIST-1 system. Here are just some of the images snapped by Spitzer:
Now with @nasa’s newest app, NASA Selfies, you can place yourself at the center of the action! (📷 credit: @nasajpl)

Happy 32nd Launch Day, Hubble!
Launched on April 24, 1990, the HST has been in operation for 32 years now -- more than twice its projected operational lifetime of 15 years! Originally scheduled for launch in 1983, it was delayed until 1986 because of engineering difficulties and was postponed again until 1990 after the loss of Challenger.
The Hubble telescope has revolutionized our understanding of not only our own galaxy but the origins of the universe itself.
