Astronomers for the first time in the history of human space exploration, snapped pictures of direct images of Neptune’s secretive auroras, marking a milestone in space exploration. Scientists had long believed that distant ice giant Neptune was displaying light-wielding shows like other worlds. Although Voyager 2 spacecraft provided fleeting summits and other worlds such as Jupiter, Saturn, and Uranus provided the same, no direct observations of Neptune’s auroras were provided. This was achieved by the James Webb Space Telescope (JWST), a state-of-the-art observatory that aimed its advanced instruments at Neptune.
James Webb Space Telescope unveils stunning images of Neptune’s aurora
Northumbria University’s Henrik Melin, the lead researcher, described how excited he was to be able to image Neptune’s auroras so stunningly thanks to Webb’s near-infrared sensitivity. “It was mind-boggling to see the auroras, and also the definition and resolution of the signature just blew me away,” said Melin. Webb’s new technology allowed astronomers to capture close-up images of Neptune’s ionosphere, the electrically charged part of its upper atmosphere where auroras are produced, to show the planet’s dazzling light spectacles for the first time.
The mystery behind Neptune’s unusual auroras
Aurorae on Earth, Jupiter, and Saturn are usually confined to the poles by magnetic field tilting, but not Neptune. This is because Neptune is tilted and offset highly off-center in terms of magnetic field orientation, a situation that causes its aurorae to appear in the unusual positions of the planetary mid-latitudes. Researchers found that the inequality of auroral occurrence stems from the rare magnetic configuration of Neptune, distinct from the other gas giants whose magnetic field is not aligned.
The JWST Near-Infrared Spectrograph was instrumental in capturing the images and analyzing the light emanating from Neptune’s atmosphere. Through breaking down different wavelengths of light, scientists can conclude fundamental physical parameters of the planet, such as temperature, mass, and chemistry. Most impressively, trihydroxygen emissions (H₃⁺) were seen, a prominent ion present in other gas giants’ auroras, Jupiter, Saturn, and Uranus. This confirms that auroras in Neptune also go through the same mechanism as the rest of the gas giants, were charged particles in the solar wind influence the planet’s atmosphere to produce radiant emissions.
JWST data reveals Neptune’s surprising atmospheric cooling and impact on auroras
Aside from viewing Neptune’s auroras, the JWST data allowed scientists to measure the planet’s temperature directly for the first time since the Voyager 2 flyby in 1989. What they discovered was unexpected: Neptune’s upper atmosphere cooled by several hundred degrees over the past few decades. Actually, 2023 temperature was about half as much as the temperature of 1989. This cooling is perhaps one explanation for how very hard it has been to discover Neptune’s auroras. Auroras result from charged particles interacting with atmospheric gases, energizing them with light. More intense and bright particles are produced when there are greater temperatures, but lower energy emissions that are not easy to discover are created in lower temperatures.
Future of aurora research on Neptune
The discovery in the study of Neptune’s auroras holds bright future potential for continued study. Since the astronomers keep looking at the planet using the JWST, they will attempt to find out more about the atmospheric dynamics of Neptune and the aurorae. “Because we’re looking out to the future and considering sending future missions to Uranus and Neptune, we now value how significant it will be to have instruments at the wavelengths of infrared light with which to continue observing the auroras,” co-author Leigh Fletcher of Leicester University said. Information collected by the JWST has uncovered an invisible realm previously unrecognized in Neptune’s ionosphere, and it provides us with a glimpse of enigmas of our solar system’s most mysterious worlds.

By 2040, India will be among the developed nations in the field of space and would have its own space station, V. Narayanan, chairman of the Indian Space Research Organisation (ISRO), said.
Speaking at the commissioning of O-ARM – a stealth technology equipment for Kauvery Hospital – here on Wednesday, Mr. Narayanan noted that the ISRO looked to place in orbit an independent 52-tonne space station by 2035. “Work is on to building a rocket the size of a 40-story building, which will take people to space…,” he added.
“India is growing in all sectors. I request doctors to adhere to ethics and values, and work to help villagers lead a healthy life,” he further said.
Aravindan Selvaraj, co-founder of Kauvery Hospital, said the O-ARM machine, installed in the hospital’s Alwarpet branch, helped doctors to precisely operate on tumours. It is especially helpful in treating brain and spine and in orthopaedic surgeries, he added.
Doctors who shared their experience said the technology’s precision would help patients get back on their feet faster, and heal better.

What cooling capacity do I need for my room size?
For small rooms (up to 110 sq. ft.), opt for 1 Ton ACs like the Carrier 1 Ton or Hitachi 1 Ton . Medium-sized rooms (111–150 sq. ft.) require 1.5 Ton models like the Voltas 1.5 Ton or Lloyd 1.5 Ton , ensuring efficient cooling without overloading energy consumption.
How important is energy efficiency in choosing an AC?
Energy-efficient models like the Godrej 1.5 Ton (ISEER 4.1) or Lloyd 1 Ton 5 Star reduce electricity bills significantly. If you live in hot climates or use the AC frequently, prioritize higher ISEER ratings and star ratings (3-Star or 5-Star) for long-term savings.
Should I invest in smart features like Wi-Fi connectivity?
If convenience matters, go for smart-enabled ACs like the Carrier Wi-Fi AC series. Features like remote control via apps or voice assistants enhance usability but come at a premium. Evaluate if these features align with your lifestyle before investing.
How critical is warranty and durability for long-term use?
Long warranties, like the Godrej 5-Year Comprehensive or Blue Star 60-Month Warranty, ensure peace of mind. Durable copper condensers with anti-corrosion coatings are ideal for harsh climates, minimizing maintenance costs and ensuring uninterrupted performance.
