The vast cloud of left over material was not completely uniform. Some areas were a little denser than others. These 'pockets' of mass had a slightly larger gravitational effect and began to attract surrounding matter to them. The once massive star region became a 'star nursery', producing many new stars from the 'ashes' of the old. Each new star eventually wandered from its nursery along with a collection of planets.
Astronomers have a good idea stars form this way because there are many star forming regions that are visible in our galaxy that are at the point in time now where our sun was 4-5 billion years ago. An easy one to spot with the naked eye is the star cluster Pleiades also known as the Seven Sisters. It is composed of large hot blue type stars and is very young at around 250,000 years old. Like the sun's siblings, the stars in Pleiades will slowly drift apart as well.
This may worth something:
From the archives: 60 Minutes' first report on solar energy, in 1979 - CBS
No matter the source of their energy issues, people have been turning to solar solutions for decades.
60 Minutes first reported on harnessing the power of the sun in 1979. At the time, the global supply of crude oil had declined in the aftermath of the Iranian Revolution. As lines grew at gas pumps, Americans looked for ways to reduce their dependence on fossil fuels.
Some turned to the sun—and wondered when the U.S. government would lead the rest of the country into a future of renewable energy. The technology was successful, they argued, and it paid for itself over time.
Scientists Claim to Have Found The First Known Extraterrestrial Protein in a Meteorite
If their results can be replicated, it will be the first protein ever identified that didn't originate here on Earth.
"This paper characterises the first protein to be discovered in a meteorite," the researchers wrote in a paper uploaded to preprint server arXiv . Their work is yet to be peer reviewed, but the implications of this finding are noteworthy.
Researchers have now revisited the meteorites that yielded the latter. Led by physicist Malcolm McGeoch of superconductor X-ray source supplier PLEX Corporation, the team focussed their search for something more.
NASA Soon to Unveil Ice-Bound Secrets of Neptune & Uranus | The Daily Galaxy
When the James Webb Space Telescope launches in 2021, NASA scientists predict they’ll observe phenomena on the ice giants, Uranus and Neptune–the least-explored category of planet in our solar system–that are totally unlike anything we’ve seen. The Neptune we currently know is a dark, cold world, whipped by supersonic winds that can reach up 1,500 miles per hour.
Like Uranus, this ice giant’s very deep atmosphere is made of a thick soup of water, ammonia, hydrogen sulfide and methane over an unknown and inaccessible interior. The accessible upper layers of the atmosphere are made of hydrogen, helium and methane. As with Uranus, the methane gives Neptune its blue color, but some still-mysterious atmospheric chemistry makes Neptune’s blue a bit more striking than that of Uranus.

Kathmandu embraces solar power to reach net zero target by 2025 - Inside Retail
Outdoor clothing and equipment retailer Kathmandu has opened its first solar-powered store in Blackburn, Victoria, and is investigating the possibility of shifting more stores in its network to solar in order to reduce its environmental footprint.
“While it won’t be possible for solar power to be rolled out across the entire store network because many stores are located in large shopping centres not suited to individual solar systems, we intend to assess which of our stores could be adapted for solar power in the future,” Dean Smith, project manager for store development at Kathmandu, said.
Freeman Dyson, from subatomic particles to the cosmos, an expansive thinker - The Boston Globe
In a career spent traversing fields as diverse as physics, biology, astronomy, nuclear energy, arms control, space travel, and science ethics, Mr. Dyson was always obliging when a journalist called him for a grabby quote about the trajectory of humanity. His ideas were reliably unorthodox; the Pulitzer Prize-winning classical composer Paul Moravec once called him ''the world's most civil heretic.''
In a profile of Mr. Dyson in 2009 in The New York Times Magazine, his colleague Steven Weinberg, a Nobel laureate, observed, "I have the sense that when consensus is forming like ice hardening on a lake, Dyson will do his best to chip at the ice."
NSW Solar + Battery Scheme Finally Kicks Off - Sort Of
“.. the pilot will be available to eligible residents who have postcodes in the areas of Cessnock, Dungog, Lake Macquarie, Maitland, Mid-Coast, Muswellbrook, Port Stephens, Singleton and Upper Hunter,” states Energy NSW .
Empowering Homes would have been a fantastic program if solar-only. Around 20.4% of NSW dwellings had panels installed as at the end of September last year (source APVI); behind Queensland (35.7%), South Australia (35%) and Western Australia (28.8%).
