SPACE.com 25 Jun 2019, 20:21 UTC On Tuesday, July 2, a lot of ocean and a few tiny bits of land will lie under a moon-blackened sun. A total solar eclipse will take place that day ... the first total eclipse of the sun since the Great American Total Eclipse of Aug. 21, 2017.
Centauri Dreams 25 Jun 2019, 17:54 UTC The mineral Cable’s team identified in the lab may account for a surface feature found in Cassini imagery in the form of orange shadings around the edges of Titan’s seas and lakes. We know that some of these areas show signs of evaporated material left behind as the liquid receded. These bright features show up in data from the spacecraft’s Visual and Infrared Mapping Spectrometer (VIMS) and Synthetic Aperture Radar (SAR) around lakes in the north polar region. The thinking is that organic molecules generated in the atmosphere and deposited on the surface dissolve in liquid methane and ethane and precipitate when it evaporates.
Universe Today 25 Jun 2019, 17:26 UTC It looks like a poster of the famous Hubble Deep Field, marked with white streaks by a child, or put away carelessly and scratched in the process. But it’s not. The white streaks aren’t accidents; they’re the paths of asteroids.
AAS Nova 25 Jun 2019, 16:00 UTC In the coming decades, there are plentiful opportunities and ideas for space-based missions that may be able to detect life on other planets — the James Webb Space Telescope (JWST), LUVOIR, the Origins Space Telescope, HabEx, and more. But, what would those signs of life look like, and what do we need to actually detect these biosignatures with confidence? These are two of the key questions astronomers face as they prepare to choose the next big space telescopes.
Bad Astronomy 25 Jun 2019, 13:00 UTC Sometimes being a science communicator with an astronomy background means trusting your instincts. In the particular case below it wasn’t like it was a huge revelation or anything, but just a fun confirmation that we do indeed understand a lot of stuff going on in the Universe. So. I’m not sure where I saw it first, maybe in my email or a link on Twitter, but I happened upon an image of an odd galaxy called NGC 4485. The image was taken using Hubble Space Telescope, and — of course — it’s jaw-droppingly spectacular.
