This is about how Jupiter looks in a modest-sized amateur telescope. You can even see a few of its ... [+] largest moons.
From Mercury to Neptune, you can spot all the solar system official planets in November's sky; in fact, you can see them all this week if you know just where to look. And yes, dwarf planet Pluto is visible as well for advanced observers. All you need is a cloud-free area, a modest telescope and some patience, but the upshot is astronomy is a quarantine-friendly activity.

Our solar system formed in less than 200,000 years - Tech Explorist
The oldest solids framed in the Solar System are calcium-aluminum–rich inclusions (CAIs), small metallic droplets later incorporated into meteorites. The ages of CAIs are considered the age of the Solar System, however which exact moment in star arrangement they correspond to has been unclear.
By observing other stellar systems that formed similarly to ours, astronomers gauge that it presumably takes around 1-2 million years to collapse a cloud and start a star. This is the first study that provides numbers on our solar system.
Isotopes suggest solar system formed in under 200,000 years
At one time it was thought that the formation of the solar system was a very gradual process, taking place across hundreds of millions of years. More recent revisions had the solar system forming over two million years, as the Sun and the planets coalesced out of a great disk of gas and cosmic dust.
The new LLNL study suggests that the transition from large cloud of gas to nascent solar system was just 40,000 and 200,000 years. This conclusion is based on an isotopic analysis of the element molybdenum in calcium-aluminum-rich inclusions (CAIs) found in carbonaceous chondrite meteorites, which are a direct record of the solar system's formation.

Famed meteorite reveals early water on Mars—and an early outer space bombardment | Science | AAAS
It was a tough fundraising pitch: Martin Bizzarro, a cosmochemist at the University of Copenhagen, needed some $500,000 to buy—and then grind up—material from one of the oldest and most valuable rocks in the world. Only this rock wasn't originally from Earth. It came from Mars.
Bizzarro's bet has now paid off handsomely. With just 15 grams of the 4.4-billion-year-old "Black Beauty" meteorite , discovered in 2011 in the western Sahara, his team has revealed a record of asteroid impacts and volcanic eruptions spanning nearly all of martian history.

Astronomical phenomenon makes it easier to see the solar system
CAPE CORAL, Fla — Friday's space x launch isn't the only out of this world event happening in the galaxy.
Celestial circumstances are underway, making it easy for you to see planets like Mercury, Venus, Saturn, and others in the sky.
While it may seem supernatural, astronomer Derek Bushazi says there's nothing really magical about it.
"They all sort of orbit the sun at different speeds, so what we have now is a nice chance alignment, so essentially all of the planets are visible," Bushazi says.
Humans May Have Appeared Before the Solar System, Study Says | The Rio Times
RIO DE JANEIRO, BRAZIL - A new study published in Science magazine points out that human beings may have existed in the universe even before the formation of the solar system. Formed 4.5 billion years ago, the system housing the Earth is basically an adolescent when compared to the universe, which scientists believe has existed for 13.8 billion years.
And, according to scientists, the human species may have been walking the Earth 100,000 years before the creation of the solar system - which would have taken 200,000 years to be completed.
