Solar physics with the Square Kilometre Array

Although solar physics is one of the most mature branches of astrophysics, the sun confronts researchers with a large number of outstanding fundamental problems. These problems include the determination of the structure ...

Melting a satellite, a piece at a time

Researchers took one of the densest parts of an Earth-orbiting satellite, placed it in a plasma wind tunnel then proceeded to melt it into vapour. Their goal was to better understand how satellites burn up during reentry, ...

Image: Instant space selfies

How many times have you taken a selfie and posted it instantly to your favourite social media channel? The Mercury Transfer Module of the BepiColombo spacecraft, currently en route to Mercury, is equipped with three 'selfie-cams' ...

SpaceX says 60 Starlink satellites will grow harder to see

SpaceX said Friday that the first 60 satellites in its "Starlink" constellation, which is intended to provide internet from space, will be less and less visible from Earth as they reach their final orbit.

Solar jobs are up in Minnesota, but down nationally

Minnesota posted an eight percent increase in solar industry jobs last year, bucking a national solar employment decline of 3.2 percent, said an annual report released Tuesday by The Solar Foundation.

Thermal testing of Solar Orbiter

A side view of ESA's Solar Orbiter as it entered a vacuum chamber for thermal vacuum testing at the IABG test facility in Ottobrunn, Germany, last month.

Mantle neon illuminates Earth's formation

The Earth formed relatively quickly from the cloud of dust and gas around the Sun, trapping water and gases in the planet's mantle, according to research published Dec. 5 in the journal Nature. Apart from settling Earth's ...

Photovoltaic array

A photovoltaic array is a linked collection of photovoltaic modules, which are in turn made of multiple interconnected solar cells. The cells convert solar energy into direct current electricity via the photovoltaic effect. The power that one module can produce is seldom enough to meet requirements of a home or a business, so the modules are linked together to form an array. Most PV arrays use an inverter to convert the DC power produced by the modules into alternating current that can plug into the existing infrastructure to power lights, motors, and other loads. The modules in a PV array are usually first connected in series to obtain the desired voltage; the individual strings are then connected in parallel to allow the system to produce more current. Solar arrays are typically measured by the peak electrical power they produce, in watts, kilowatts, or even megawatts.
