In July, NASA’s Juno probe sent back close-up photos of the big Red Spot on Jupiter, and they were impressed.
The big red spot is a giant storm, the width of which is larger than the size of the Earth. It has been roaming the atmosphere of Jupiter for at least 350 years (and is shrinking). By comparison, the longest storm on Earth lasted only 31 days (Hurricane John, 1994).
In the middle of July, Juno flew 9,000 km from the storm, or about 1.6 million km closer than the previous probe.
Juno took these 7 photos on the 7th flight of gas giant, at a speed of about 210 thousand km / h. Therefore, it is difficult to take photos of this size.
After each Juno fly over Jupiter (53.5-day cycle), NASA publishes raw images (not processed) and a photo editing community enthusiastically turn them into works with vivid colors. .
Below are new images of the Great Red Spot, with results worth reviewing from previous Jupiter approaches.
“This massive storm has stirred the largest solar system in centuries,” Scott Bolton, who led Juno mission, said in a NASA statement.
At the nearest point, Juno flew so close to the red spot that the camera was not wide enough to capture the full view of the storm. The photo below shows the estimated angle that Juno could take at that time.
The probe also takes zoom shots at 34 mph – the equivalent of going across the entire American continent in just over a minute. The result is long sequences of very detailed images.
The 3D images below show the depth of cloud layers during a storm. Wind here blows up to 644 km / h.
To help viewers compare sizes, artist Seán Doran has placed the image of the Earth in the big Red Spot.
Another person has stitched the photo below. Between a 1979 photo and a new one, with the probe’s flight distance. The object at the bottom is Ganymede, the moon of Jupiter.
The big red spot is not the only super typhoon on Jupiter to be photographed. The photo below is a “small red spot” located in the temperate northern region.
In his previous visits, Juno also took remarkable photos of storms and clouds on Jupiter. This picture of an egg-shaped tornado was taken on February 2.

Juno also captures Jupiter images from a distance, like the southernmost image on May 19 below …
The South Pole looks directly, the blue swirling storms in the picture can be up to 960 km wide, almost the same state of Texas.
Sometimes Juno also points the camera out to Jupiter and takes photos of the universe. The faint line in the middle of the photo below is the belt of dust and Jupiter, far away is the constellation Orion.
The Juno probe will not fly forever on Jupiter, NASA plans to send it into the planet’s atmosphere in 2018 or 2019, similar to the Huygens probe that landed on Saturn’s moon Titan. in 2005
USA: The company recommends transplanting small microchips with rice seeds into employees
A technology company in Wisconsin is asking employees to implant microchips to facilitate scanning when entering a building and buying food at work. The decision to implant or not is up to each person.
The company, called Three Square Market, specializes in providing technology for recess rooms or micro markets (a vending corner, usually food, for foyer rooms or in company offices). Currently over 50 employees have agreed to carry out this transplant.
The tiny chip, about the size of a grain of rice, uses RFID (Radio Frequency Identification, radio identification) technology and will be implanted between the thumb and index finger, “just a few seconds,” the announcement. from the company said. The company will also pay for this (about US $ 300 per person).
The company hopes microchip will help employees pay quickly for items, enter and exit the building, and log on to the computer just by scanning their hands.
“We anticipate that RFID technology will invade everything from buying food at the foyer to opening doors, using photocopiers, logging in to office computers, unlocking phones, sharing. business cards, storage of health information and payment at other RFID gateways, ”CEO Todd Westby said in a company statement.
Employees are not required to implant chips, and Mr. Westby said there is no GPS tracking function on it.
RFID technology on these microchips is often used to track goods in the supply chain, find lost cats and dogs and accurately time in marathons.
Security is the most worrying issue, because transplants create additional opportunities for hackers to steal data, or companies can secretly spy on employees.
Epicenter, a company that had its employees “chip implanted” a few months ago, said it did not store or track such data at the company. However, it is not clear whether the data is stored at BioHax (RFDI chip service provider) or not; or may Epicenter change this hosting policy.
