For the first time ever, astronomers have directly imaged multiple planets orbiting a sunlike star.
The European Southern Observatory's Very Large Telescope (VLT) in Chile photographed two giant planets circling TYC 8998-760-1, a very young analogue of our own sun that lies about 300 light-years from Earth, a new study reports.
"This discovery is a snapshot of an environment that is very similar to our solar system , but at a much earlier stage of its evolution," study lead author Alexander Bohn, a doctoral student at Leiden University in the Netherlands, said in a statement.

Braking Climate Change With a Mini Solar System: Do We Have to Become Solar Guerrillas?
Of course we all know that a lot has to change on this earth so that humans and animals have a viable future on this planet. In order to achieve this goal, you can and must bring about a system change in the political and economic area, or you have to become active yourself.
One way to make a personal contribution to energy change is to generate electricity from solar energy using a mini PV system (PV, Photo Voltaic). These are often referred to as balcony power plants. They supply electricity from sunlight to use it for their own purposes free of charge. The electrical consumers such as refrigerators, devices in standby etc. are then completely or partially operated with the self-generated electricity.
Exocomets from a Solar System Perspective
Exocomets are small bodies releasing gas and dust which orbit stars other than the Sun. Their existence was first inferred from the detection of variable absorption features in stellar spectra in the late 1980s using spectroscopy. More recently, they have been detected through photometric transits from space, and through far-IR/mm gas emission within debris disks.

Duke Energy Renewables completes second 200-MWac solar system in Texas
Duke Energy Renewables , a subsidiary of utility Duke Energy, started commercial operations of its 200-MW ac Rambler Solar project in Tom Green County, Texas.
The Rambler Solar project is the second 200-MW ac Texas solar facility that Duke Energy Renewables has brought online this year, bringing its total Texas solar portfolio to over 500 MW ac in operation. In early July, the company announced the commercial operation of its Holstein Solar project in Nolan County.

Scientists identify asteroids of interstellar origin moving in our Solar System- Technology News,
Scientists at São Paulo State University's Institute of Geosciences and Exact Sciences (IGCE-UNESP) in Rio Claro, Brazil, have recently spotted 19 asteroids of interstellar origin. These asteroids are classified as Centaurs, which are outer Solar System objects that revolve around the Sun in the region between the orbits of Jupiter and Neptune.
The study titled An interstellar origin for high-inclination Centaurs was supported by FAPESP and has been published in the Royal Astronomical Society's Monthly Notices.
Scientists rediscover 'lost planet' more like the ones in our own solar system - CNET
The NGTS facility in Chile is working on tracking down exoplanets located in their stars' "Goldilocks" zones.
Exoplanets, those mysterious planets that dwell outside of our solar system, are always fascinating, but humanity is particularly interested in those located in their stars' habitable zones where liquid water might exist. A new method for detecting exoplanets could help scientists spot many more of these intriguing, distant worlds.
This is a cosmic detective story. TESS first located the planet by seeing a subtle dip in brightness when it crossed in front of its star. But TESS only stares at a section of space for a limited period of time, usually 27 days. Scientists like to observe two dips in brightness to confirm an exoplanet's existence, but some of those planets take longer than 27 days to circle back around.

At the heart of understanding our space environment is the knowledge that conditions throughout space — from the Sun to the atmospheres of planets to the radiation environment in deep space — are connected.
Studying this connection — a field of science called heliophysics — is a complex task: Researchers track sudden eruptions of material, radiation, and particles against the background of the ubiquitous outflow of solar material.
