Traveling through space can be a bumpy ride! Join Govert Schilling on a scenic road trip across southern Africa filled with craters and meteorites.
Govert Schilling chronicles his travels to astronomical observatories across South Africa, the future site of the Square Kilometre Array.
Hubble has spotted more than 100 small, faint galaxies in the young universe, common as dust bunnies but previously out of reach of even the best telescopes.
Explore two unique astronomical sites that lie under the dark skies of Namibia - the HESS high-energy array and the Africa Millimeter Telescope.
Astronomers analyzing a new sky survey have found that the distribution of dark matter in the modern universe is smoother than predicted from observations of a far younger universe.
Despite an 11th-hour scramble due to an unexpected in predictions, NASA's flying observatory was in the right place at the right time on June 29th as distant Pluto briefly covered a 12th-magnitude star.
S&T contributing editor Govert Schilling tells the story of his recent expedition to the unique science laboratory located at the inhospitable South Pole.
It's not easy to get to the Murchison Radio Observatory in Western Australia. Being in one of the most remote regions of the country means there's hardly any radio interference that might otherwise compromise the astronomical observations. It's one of the most radio-quiet zones on the planet.
The latest 500 planet candidates from the Kepler mission are just part of the story. But Terra II remains elusive.
Dutch-born planetary scientist and asteroid hunter Tom Gehrels passed away on July 11th. Sky & Telescope contributing editor Govert Schilling shares his memories of a unique person.

Astronomers have found the smallest transiting exoplanet yet, with a silhouette only about 1.7 Earth diameters wide. It's also the fastest-orbiting planet known, with a "year" lasting 20 hours.
Type 1a supernovas are crucial for measuring how the expansion of the universe has been changing. But no one knows for sure exactly what they are.
A 45-year mystery solved? Scientists using the new Pierre Auger Observatory say they've finally tracked down where ultra-high-energy cosmic rays "tennis ball particles" are coming from.
A ripple in the cosmic background radiation hints at an irregularity in spacetime. . . maybe.
Did a colossal collision in the asteroid belt 160 million years ago doom the dinosaurs? A just-published analysis argues strongly for exactly that.
Mira, the closest and brightest of the red long-period variable stars, has thrown off a gassy hood and a comet-like tail so big that if you could see them, they would overflow your telescope's field of view.
Astronomers have assembled an armada of telescopes to observe Uranus in a way that hasn't been possible since the 1960s.
With an aperture of 10.4 meters, Spain's new Gran Telescopio Canarias is about to assume the title.
Astronomers have uncovered a fascinating heavy object orbiting close to its star. The problem is, they aren't sure what to call it.
It's official: our solar system has eight planets, and Pluto is not one of them according to the International Astronomical Union.
Telescopes as large as 20, 30, and even 100 meters are now on the drawing boards.
The latest results from two comprehensive galaxy surveys independently confirm the important role of dark matter and dark energy in the evolution of the cosmos.
Like mosquitos hovering around a mountain, small black holes swarm around the supermassive black hole in the core of the Milky Way. According to a team led by Michael P. Muno (University of California, Los Angeles), there may be as many as 20,000 stellar-mass black holes lurking within a three-light-year-wide sphere surrounding the 3-million-solar-mass behemoth…
