Realme Narzo 80 Pro 5G is now available in a new finish in India. The handset was launched in April in the country alongside Realme Narzo 80x 5G with two colour options — Racing Green and Speed Silver. The new colour variant was introduced as part of Realme’s seventh anniversary celebrations. The Realme Narzo 80 Pro 5G runs on MediaTek Dimensity 7400 SoC and features a 50-megapixel dual rear camera unit. It carries a 6,000mAh battery with 80W wired charging support.

Realme Narzo 80 Pro 5G Nitro Orange Variant Price in India

Realme Narzo 80 Pro 5G price in India is set at Rs. 20,499 and Rs. 22,499 for the 8GB + 256GB and 12GB + 256GB RAM and storage variants, respectively. The Nitro Orange colour option has been launched in India to mark the company’s seventh anniversary.

The company is offering a coupon discount of Rs. 1,000, which will bring the effective price of the 8GB and 12GB memory variants down to Rs. 19,499 and Rs. 21,499, respectively. The latest colour variant of Realme Narzo 80 Pro 5G is up for grabs via the Realme India website and Amazon. 

The new colour variant will be available alongside the Racing Green and Speed Silver colour options that have been available in India since the phone’s debut in April.

Realme Narzo 80 Pro 5G Specifications

The Realme Narzo 80 Pro 5G runs on Android 15-based Realme UI 6.0 and boasts a 6.77-inch full-HD+ (1,080×2,392 pixels) AMOLED display with up to a 120Hz refresh rate and 4500nits peak brightness. It runs on a 4nm Dimensity 7400 SoC paired with up to 12GB of LPDDR4X RAM and up to 256GB of UFS 3.1 onboard storage

The handset has a dual rear camera unit that comprises a 50-megapixel primary sensor with optical image stabilisation (OIS) support and a 2-megapixel secondary sensor. It has a 16-megapixel selfie shooter.

The Narzo 80 Pro 5G has an in-display fingerprint sensor for biometric authentication. It is claimed to have military-grade (MIL-STD-810H) durability. It packs a 6,000mAh battery with 80W wired charging and 65W reverse charging support.

NASA’s Juno mission has discovered a world of cyclones at Jupiter’s north Jovian pole, a region of cooler stratospheric haze. The cyclones drift to the pole through a process the researchers refer to as “beta drift” via JunoCam and Jovian Infrared Aurora Mapper. The cyclones oscillate around their centres and can drift clockwise around the pole. Juno has also been making recurring flybys of the innermost Jovian moon, Io, revealing evidence of subterranean magma flows below its surface. These cooling flows could explain how Io’s volcanoes erupt, as about 10% of the moon’s subsurface has these flows.

Juno Spots Colliding Jupiter Cyclones and Magma Beneath Io’s Surface

As per the data presented by NASA at the European Geosciences Union General Assembly on April 29, Juno has observed a large central cyclone over 1,800 miles wide, encircled by eight slightly smaller cyclones. These weather systems, blowing at speeds over 100 miles per hour, interact through a phenomenon called beta drifts — similar to Earth’s cyclones but progressing to Jupiter’s pole.

Once enabled, researchers could visualise both visible and thermal activity in Jupiter’s atmosphere. The cyclones stabilise one another and slowly push in the same direction around the pole—in a clockwise direction, as the researchers noted. Jupiter’s cyclones differ from those on Earth since they do not weaken over time at the poles, when the planet has a different atmospheric makeup.

At the same time, exploring Io with Juno has made another discovery: that beneath the surface of the moon lie hidden flows of magma. By pairing infrared and microwave data, scientists picked up warm lava from a large eruption on Dec. 27, 2024. The volcano remained active through Juno’s next flyby in March and is expected to erupt again in May. These discoveries mark the most energetic volcanic eruption ever observed on Io.

The detection of subsurface magma confirms Io’s surface is constantly being renewed. Scientists calculate that 10% of the moon’s interior contains slowly cooling lava. These lava flows help transport heat from Io’s interior to the surface.

Some of the brightest lights in the universe shine from some of its darkest corners — so-called supermassive black holes. Invisible to the human eye, these high-energy powerhouses light up the cosmos with emissions that are detected by space telescopes. Thousands of such light sources have been discovered with NASA’s Fermi Gamma-ray Space Telescope, which has been observing since 2008. These aren’t just stars — they are active galactic nuclei (AGN) where large gravitational forces fling matter around black holes, creating intense radiation blasts all across the electromagnetic spectrum.

Blazars and AGN Jets Reveal How Black Holes Shape and Light Up the Universe

As per NASA’s report ,observational data, black holes lurk at the centres of most galaxies and are hundreds of thousands to billions of times the mass of the sun. In AGN, gas and dust fall into an inward-spiralling disk. Second, the disks experience friction and magnetic forces that produce light from radio to gamma rays. About one in ten AGN produce powerful jets of particles that move at nearly the speed of light, and it’s still a mystery to scientists how material so close to the event horizon is accelerated in the jets.

, the type of AGN observed depends on its orientation relative to Earth. Radio galaxies shoot their jets sideways, while blazars aim them nearly straight at us, making them appear especially bright in gamma rays. Fermi’s sky surveys show that more than half of the thousands of gamma-ray sources it has recorded are blazars, giving researchers vital clues about the energetic mechanics behind these cosmic light shows.

AGN are more than just bright; scientists are attracted to them for what they tell us about cosmic history. AGN existed in the early universe and were probably important in modulating galaxy evolution. Astrophysicists will use observations and analyses of the conditions directly around these black holes to learn more about the structure and history of the universe itself.

The paradox is acute: black holes are famous for eating up all the light and matter they can latch onto, but they lie behind some of the most luminous phenomena seen in space. Through missions like Fermi, scientists are adjusting the picture of the universe, in which some of its darkest origins can sparkle the most.
