Hubble Captures Stunning Photos of Auroras the Size of Earth on Jupiter

jupiteraurora_feat

Photographers go gaga over the Aurora Borealis on Earth, capturing amazing timelapses and photographs and even live video from 35,000 feet. But no Earthly aurora will compare with what Hubble just captured swirling atop Jupiter.

The photo is breathtaking, all the more so once you understand that the aurora you’re looking at in the image below covers an area larger than our Earth.

These light shows at Jupiter’s poles actually never stop, revealed NASA, they’re always available for study and capture. The image below was created by combining an earlier Hubble photograph of Jupiter itself with new images of the auroras captured by the Hubble Space Telescope Imaging Spectrograph at the far end of the ultraviolet light spectrum.

The image, released earlier today, has captured the world’s imagination just as NASA spacecraft Juno is arriving at Jupiter after a 5 year long voyage.

Among other things, the spacecraft will monitor these massive auroras created by the solar system’s largest and most powerful magnetosphere, while Hubble takes pictures of them every day to see what impact solar wind and other conditions exert.

Here are some composite video sequence Hubble released alongside the standalone image:

“These auroras are very dramatic and among the most active I have ever seen,” principal investigator of the study Jonathan Nichols, from the University of Leicester, UK, said in a statement. “It almost seems as if Jupiter is throwing a fireworks party for the imminent arrival of Juno.”

A fireworks display worthy of the largest planet in our solar system.

SanDisk Announces World’s Fastest 256GB microSD Card

Extreme_microSDHC_U3_256GB

The memory card wars are fought on two playing fields: size and speed. And SanDisk is claiming victories on both fields today with the release of the 256GB SanDisk Extreme microSDXC UHS-I card—the world’s fastest 256GB microSD card.

For a long time it seemed microSD wasn’t getting much R&D love, but with the rise of action cameras and especially drones that depend on these cards, the money has returned and the advancements keep coming. Samsung’s recently-released 256GB card was the “highest capacity microSD card in its class,” and now SanDisk is pairing that high capacity with some much-needed speed.

Capable of storing up to 14 hours of 4K video, the card boasts “unmatched transfer speeds” up to 100MB/s and write speeds up to 90MB/s. SanDisk is earmarking the Extreme microSDXC UHS-I card as “ideal for high-performance drones, action cameras, and 4K-capable smartphones, among other devices.”

Alongside the super-fast 256GB Extreme card, SanDisk is also releasing a slightly slower but still speedy 256GB Ultra microSDXC UHS-I Premium Edition card. This one is geared more towards typical consumers. Boasting up to 24 hours of Full HD video storage and transfer speeds up to 95MB/s, SanDisk says this one is “ideal for Android-based smartphone and tablet users who don’t want to worry about running out of space on their devices.”

Both cards are also built to withstand some punishment. They’re waterproof, temperature-proof, shock proof, and X-ray proof… although, curiously, SanDisk didn’t mention if they’d survive a trip through your digestive system.

The Extreme card will be available globally sometime “in the fourth quarter of this year” for $200, and the Ultra Premium Edition arrives in August for $150.

23 Star Struck Images of Celestial Subjects

We can be star struck in more than one way. Celebrity sightings of famous Hollywood stars is one way, the other is by the celestial stars themselves – literally!

Let’s look at a few images of celestial subjects and see how they can be captured in photographs:

Full Specs and New Photo of Fuji X-T2 Leaked

xt2_feat_1

Fuji is expected to officially announce the new X-T2 on July 7th, but there may not be much mystery left when the announcement lands. A full spec list and new photo have just leaked and, if they’re accurate, they don’t leave much to the imagination.

The photo above appeared on digicame-info, and while this is not the first time we’ve seen photos of the X-T2, DI also released the most comprehensive spec list yet.

According to them, the X-T2 will sport a 24.3MP sensor, X Processor Pro engine, 4K at 30fps and 1080p at 60fps, 1/8000 sec max shutter and 1/32000 max electronic shutter, ISO range from 200 to 12800, hybrid 325-point AF system, 2.36M-dot EVF with 100fps refresh rate, tilting 3-inch 1.62M-dot LCD, Dual UHS-II supported SD card slots, +/-5 exposure comp, and 256-segment metering.

We have no reason to doubt digicame-info’s specs—they’re consistently right when announcing specs and leaking images this close to an official announcement—but we won’t have to wait long to confirm. X-shooters should mark July 7th on your calendars and keep an eye out for more leaks in the coming days.
