To celebrate the 31st birthday of the Hubble space telescope NASA has released a stunning picture a giant star ‘waging a tug-of-war between gravity and radiation to avoid self-destruction’. The star in question is AG Carinae, and it’s shown surrounded by a glowing pink cloud of dust and gas that measures five light-years across.
According to NASA the star was created from giant eruptions that occurred 10,000 years ago, and which blew out the star’s outer layers. This left a constant battle between the radiation pressure from the star pushing matter outwards, and gravity pushing it back again. When the outward pressure is more powerful than gravity the star expands, and creates colorful nebula as seen here.
AG Carinae is truly massive, and is thought to be 70 times bigger than our Sun and a million times brighter. The picture was captured by the Hubble Space Telescope using both visible and ultraviolet light, which it can do as it is beyond the Earth’s atmosphere.

The GFX 100S fits most of the capabilities of the GFX 100 into a smaller and more affordable body. We’ve tested what the camera offers to see who it might make sense for.
The Polaroid Go uses a new square-format i-Type ‘Go’ instant film that’s a miniature version of the iconic Polaroid 600 film used in the original Polaroid One Step.
The Sony Alpha 1 is Sony’s flagship mirrorless camera for, well, just about anything. With a 50MP sensor, it gives you tons of resolution, but it also lets you fire off burst images at 30 fps for fast action sports. Add in 8K video capture and you have a really impressive package.
The DJI Air 2S is exactly what many drone enthusiasts have been asking for: a consumerdrone with a 1″-type camera sensor that’s budget-friendly. Does it live up to the hype? In our opinion, yes.
DxO has just released PureRaw, a simple, standalone program that can automatically apply its high-quality lens corrections and impressive noise-reduction algorithms to your Raw files, and then pass those Raw files off to your favorite editing app. We’re pretty impressed by it – find out why in our review.
