In an update to the category “wildlife reactions to drones,” two red-tailed hawks in Brooklyn, New York’s very large and wooded Prospect Park recently attacked an illegal drone. The incident was reported by a birdwatcher, according to the newspaper DNAInfo. Prospect Park and Central Park in New York are known for having resident hawks, and two of them were likely the ones involved.
Rob Bate, who has been president of the Brooklyn Bird Club for the last three years, saw pilots launch the drone in a large meadow (the Nethermead). Shortly afterward, hawks set upon the machinery. Bate noted that the birds were in a “stoop” position, which signals an attack mode; they had their wings folded.
“They were really upset,” as Bate was quoted by DNAInfo. “They see a drone in the air, they take it as a competitive predator, like another hawk that’s coming into their territory. And [the drone] doesn’t behave right and it doesn’t go away and they get more excited. And they were going after it.
Dark ghost shark (Hydrolagus novaezealandiae) and the pale ghost shark (Hydrolagus bemisi), both are shortnose chimaera of the family Chimaeridae, found on the continental shelf around the South Island of New Zealand in depths from 30 to 850 m.
Both ghost shark species are taken almost exclusively as a bycatch of other target trawl fisheries

Scientists Make New Form of Gold That’s Nearly as Light as Air
Researchers in Switzerland have been able to produce gold foam that is almost as light as air. In fact, 98% of it consists of air; the rest is made up of 20-carat gold and milk protein. According to materials scientist Raffaele Mezzenga from ETH Zurich, this gold aerogel is a thousand times lighter than any other gold alloy, is lighter than water, and is almost as light as air itself.

Before US astronaut Scott Kelly returned from his year-long mission aboard the International Space Station, he shared photos of his very last sunrise in space.
I think you need to see the full photos, in all their glory:

I should never have downloaded NASA’s Eyes. Now all I want to do is watch planets and galaxies all day.
Nor should I have checked out Experience Curiosity. Now I wanna cruise all over Mars.
Or the website where you can see the ISS (International Space Station) orbiting Earth in real time.
And yes, I linked all of those because I want everyone to join in the “oooh, shiny planets and galaxies!” :D
