NuSTAR Stares at the Sun
Flaring, active regions of our sun are highlighted in this image combining observations from several telescopes. High-energy X-rays from NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) are shown in blue; low-energy X-rays from Japan's Hinode spacecraft are green; and extreme ultraviolet light from NASA's Solar Dynamics Observatory (SDO) is yellow and red. All three telescopes captured their solar images around the same time on April 29, 2015. The NuSTAR image is a mosaic made from combining smaller images.
The active regions across the sun's surface contain material heated to several millions of degrees. The blue-white areas showing the NuSTAR data pinpoint the most energetic spots. During the observations, microflares went off, which are smaller versions of the larger flares that also erupt from the sun's surface. The microflares rapidly release energy and heat the material in the active regions. NuSTAR typically stares deeper into the cosmos to observe X-rays from supernovas, black holes and other extreme objects. But it can also look safely at the sun and capture images of its high-energy X-rays with more sensitivity than before.
Scientists plan to continue to study the sun with NuSTAR to learn more about microflares, as well as hypothesized nanoflares, which are even smaller. In this image, the NuSTAR data shows X-rays with energies between 2 and 6 kiloelectron volts; the Hinode data, which is from the X-ray Telescope instrument, has energies of 0.2 to 2.4 kiloelectron volts; and the Solar Dynamics Observatory data, taken using the Atmospheric Imaging Assembly instrument, shows extreme ultraviolet light with wavelengths of 171 and 193 Angstroms.
Note the green Hinode image frame edge does not extend as far as the SDO ultraviolet image, resulting in the green portion of the image being truncated on the right and left sides.

Kepler has been amazing to discover new planets and make some incredible moves forward in space exploration, but yesterday TESS) launched ushering a new level of excitement. Also waiting for and the James Webb Space Telescope launch in just a few years. the details and light gather capabilities will reveal 10 fold what Kepler has been able to do.
Can't wait to see the images and data coming back.

Astronauts aboard the International Space Station captured this photo while flying over the western United States. The wide field of view stretches from the Sierra Nevada of California to the Columbia Plateau of Oregon and the Snake River Valley of Idaho. Lake Tahoe is nestled on the border of California and Nevada.3 -

This is the Surface of a Comet
Back in 2014, the Rosetta spacecraft captured the world’s imagination by arriving at a comet and snapping the first-ever photos of a comet’s surface. Now here’s something that’s even better: a series of photos turned into a motion picture of what it’s like on the comet at ground level.2 -

Interesting update on space mining as it moves forward. Good concept for creating mining probes that can scan for water which will be broken down to elements and the Hydrogen used as interstellar fueling stations for longer and further missions. Also some looking to mine metals and elements, but the fueling stations work solves a very large stop-gap in space exploration. Currently solar sails and the like cannot harness enough energy to move the needle forward for deep space exploration.
Anyway, good short article I saw this morning.
