The largest planet in the solar system-twice as much as all other planets combined. This enormous world was formed from the same clouds of dust and gas that became our sun and the rest of the planet.
But Jupiter Was the eldest son Of our planetary family. The massive gravitational field of the first planet, Jupiter, most likely formed the rest of the entire solar system.
Jupiter may or may not have played a role in the position where all planets orbit around the sun. This is because the asteroid belt is a vast area that can be occupied by other planets. Jupiter’s gravity.
Gas giants such as Jupiter also throw entire planets out of the solar system or head towards stars.
Millions of years later, the formation of Saturn probably helped Jupiter escape this fate.
Jupiter can also act as a “comet catcher”. Otherwise, comets and asteroids that could fall into the inner solar system and attack a rocky world like Earth would instead be captured by Jupiter’s gravitational field and ultimately Jump into the clouds of Jupiter.
But at different times in Earth’s history, Jupiter May have had the opposite effect, Throwing an asteroid in our direction-it’s generally a bad thing, but water-rich rocks that lead to the blue planet we know today may have entered Earth.
Jupiter is a window into our solar system’s past. The past, literally shrouded under Jupiter’s clouds, is the reason why Juno, the spacecraft currently orbiting Jupiter, was so named. Mythical Jupiter’s wife Juno was able to peek into the cloud cloak that Jupiter uses to conceal himself and his injustice.
But in this case we are looking at our own history through the clouds of Jupiter. Juno entered Jupiter’s orbit on July 5, 2016 after traveling for almost five years to reach the gas giant.
Falling into Jupiter’s gravitational well, Juno reached a speed of 210,000 km/h. This is one of the fastest speed records ever set by any human-made object.
Juno is on a very eccentric 53-day orbit. During the Perijove or nearest orbital approach, Juno scans Jupiter at an altitude of 4,200 km, then sweeps 8.1 million km outward. Juno’s orbit is designed to navigate the weak areas of Jupiter’s incredibly powerful magnetic field.
Second power over the sun itself, Jupiter’s magnetic field accelerates high-energy particles emanating from the Sun, creating a powerful band of radiation surrounding the planet.
In addition to agile navigation, Juno’s electronics are enhanced against radiation through a “radiation vault”, a 1 cm thick titanium shell that houses sensitive scientific equipment.
One of the devices that dazzle us all on Earth is JunoCam. RGB color cameras visually image Jupiter’s clouds as the probe buzzes each orbit in 2 hours, consuming as little Jupiter’s radiation time as possible.
Most recently, Juno completed Perijove 29, some photos published by “Software Engineer, Planetary and Climate Data Wrangler, Scientific Data Visualization Artist”. Kevin Gil.

JunoCam isn’t really part of Juno’s main science mission. However, the camera serves the main function. Let Juno travel with us.
I think it’s really great. Sometimes astrophotography is more thought of as art than science.
But as an astrophotographer, I believe that this image inspires future scientists, raises a general awareness of ongoing scientific missions and public support for science funding. Speaking of which, what has our science discovered about the largest and greatest worlds?
One of Jupiter’s greatest mysteries is in its heart. Juno helped solve the ongoing debate about how Jupiter formed in the planetary science community.
There were two possibilitiesThe first is that Jupiter began as a rocky world, a nucleus that is about 10 times the mass of the Earth. The gravitational force of this nucleus attracted the surrounding hydrogen and helium until the formation of Jupiter as we know it. Its original rocky world was buried under a swirling vortex.
The second possibility is that the vortex of the rotating circular planetary disk of our early solar system collapsed on its own and Jupiter formed directly without a rocky core. Both theories account for different conditions when the solar system begins. Juno is not a solid core, but “ambiguous” or “Dilution“main point.
Jupiter appears to have been formed from a rock body, but its core is spread throughout Jupiter’s interior rather than being located at the center of the planet.
The dilution of the nucleus appears to be the result of a massive planet-sized impact on Jupiter that broke the initial nucleus and spread it over half the diameter of Jupiter.
Imagine being there for an event like that. Jupiter is swallowing up planets in our solar system that we never knew. The history of our place in space has been revealed.
We also learned that Jupiter’s winds dive deep beneath the outer clouds, the Great Red Spot is hundreds of kilometers deep, and from Jupiter’s North Pole and Antarctica we have seen huge cyclones capable of swallowing the country.

Jupiter is currently the brightest object in the night sky after sunset. If the sky is clear and you can see, look south!
Remember that the bright spot is a huge world hundreds of times the size of the Earth and millions of kilometers away, but potentially one of the key elements of your existence. Jove is amazing.
NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.
Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.
She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.
Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.
“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.
It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.
Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.
Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.
Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.
“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.
He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.
Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.
TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.
Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.
Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.
The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.
The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.
It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.
Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.
Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.
Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.
Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.
Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.
The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.
Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”
Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.
“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.
B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.
Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.
Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.
Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.
“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”
Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”
“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.
Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.
“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
This report by The Canadian Press was first published Sept. 9, 2024.
