Oldest planet in our solar system?

#planet #space #SolarSystem #Jupiter #age

So the largest planet in our Solar System is also the oldest planet in our Solar System. Jupiter. The planet was formed only within four million years after the formation of the Sun.

Considering no physical samples of Jupiter is available like of Earth, Mars, moon, asteroids, etc., isotope signatures of meteorites (derived from asteroids) were used to determine Jupiter’s age.

By looking at tungsten and molybdenum isotopes on iron meteorites, scientists found that meteorites are made up from two genetically distinct nebular reservoirs that coexisted but remained separated between one million and 3-4 million years after the solar system formed.

Thus the best explanation is that Jupiter was formed, which opened a gap in the disc and preventing the exchange of materiel between the two reservoirs.

Now we know the oldest planet in the Solar System. I wonder how old the other planets such as Saturn and Neptune are. It’s wonderful that we are knowing more and more about space as we explore.

Juno findings of Jupiter

#Juno #Jupiter #space #spacecraft #planet #solarsystem #MWR #cyclones

After spending five years to reach Jupiter and settle itself into Jupiter’s orbit, Juno has completed 10 month long journey in the orbit. Juno has since been sending images and data on Jupiter.

Recently, Juno sent its first science results which shows Jupiter as a complex, giant and turbulent world, with cyclones as massive as the Earth itself and a mammoth, lumpy magnetic field. Both of the Jupiter’s poles are covered in Earth-sized cyclones that are densely clustered and rubbing together.

Also, according to the data from Juno’s Microwave Radiometer (MWR), Jupiter’s iconic belts and zones are mysterious, with the belt near the equator penetrating all the way down, while the belts and zones at other latitudes seem to evolve to other structures. It also suggests that ammonia is quite variable and increases as we go farther down.

It is amazing to know more about other planets in the Solar system, and considering we already built that capability a decade ago, and now we are looking forward to send a manned mission to Mars, just shows how technology has evolved and yet there is so much to achieve.

 

Another Great Spot on Jupiter

#space #Jupiter #NASA #GreatColdSpot #GreatRedSpot #planet

Another large spot with a length as much as 24,000 kms and a width of 12,000 kms was discovered by scientists. The spot lies in the upper atmosphere and is much cooler than the hot surroundings, a reason it is named Great Cold Spot, in contrast with the Great Red Spot.

The Great Cold Spot is much more volatile than the Great Red Spot and has reappeared for as long as over 15 years.

Jupiter’s upper atmosphere may hold other features. Scientists will be on the lookout for them while also studying the Great Cold Spot in greater detail, using ground telescopes as well as NASA’s Juno spacecraft in orbit around Jupiter.

Watch Jupiter in the sky!

#planet #space #Jupiter #Earth #Sun #opposition

It is a known fact all planets revolve around the Sun. During the course of journey around the Sun, the position of Earth & Jupiter is that they will have face off which is known as Opposition. That is to say, an observer can easily located Jupiter by looking opposite direction to the sunset in the evening or sunrise in the morning. Jupiter will be at its closest approach and would appear more big and brighter than usual.

The opposition will be for only one day, April 9 (Mark your calendars!). The opposition occurs every 13 months, i.e. the previous one occurred on March 8, 2016 and the next one will occur on May 9, 2018. But really, why wait another year?

Juno orbiter races by Jupiter

#NASA #Jupiter #JunoOrbiter #spacecraft #space #exploration #SolarSystem

NASA’s Juno spacecraft sailed over Jupiter’s cloud tops early Monday, the fourth time the solar-powered probe has approached the giant planet and collected science data since its arrival last July 4.

At the present trajectory, the Juno orbiter arcs out to a distance of several million miles from Jupiter and then comes back for a high-speed encounter. This happens once every 53 and a half days. During the flyby, Juno passes about 4,400 kilometers over Jupiter’s cloud tops at a speed of 57.8 kilometers per second.

According to NASA, all of Juno’s science instruments are working fine currently. Although engineers detected problems with check valves inside the propellant pressurization system in October, thus avoiding that particular propulsion system in any future use.

Juno’s primary mission is to study Jupiter’s intense magnetic field and investigate the gas giant’s deep interior structure, revealing insights about its atmosphere and probing for a rocky core. After February 2018, the ground controllers are planning to intentionally crash the spacecraft into Jupiter’s atmosphere, avoiding the possibility of contaminating one of Jupiter’s potentially habitable moons.

Search for alien life on moon Europa

#NASA #Jupiter #Europa #space #moon #water #life

NASA announced that it will be sending a rover to the Jupiter’s moon Europa. The mission will take place in 2020s, and will take around 6-7 years to reach the destination. NASA aims to search life on the icy moon, since scientists believe that Europa holds liquid water beneath its icy crust and oceans on Europa are twice larger than on Earth.

The rover, named Europa Clipper, will determine if Europa is habitable by checking the necessary ingredients required to live: liquid water, chemical ingredients and energy sources sufficient to enable biology.

After reaching the surface of the moon, the rover is supposed to dig 10 centimeters into the surface, and look for possibility of life, and bring at least 10 samples back to the Earth for testing and record environmental factors suitable for the next rover.

I am so excited about the numerous missions to Mars, the Sun and now Europa. It just hows how much science is growing in our current world, and how people are so curious about things around us.
