An artist's conception of a black hole binary in a heart of a quasar, with the data showing the periodic variability superposed. The central regions of many glittering galaxies, our own Milky Way included, harbor cores of impenetrable darkness—black holes with masses equivalent to millions, or even billions, of suns. What is more, these supermassive black holes and their host galaxies...
Holes in an iceberg News.science360.gov.org
Interesting holes in an iceberg in Antarctica. The National Science Foundation runs the U.S. Antarctic Program (USAP). In addition to maintaining three U.S. research stations on the continent, USAP supports research projects in an array of scientific disciplines including, for example, aeronomy and astrophysics, biology and medicine, geology and geophysics, glaciology, and ocean and c...

The above photo shows a subtle difference between the time that's based on the instantaneous position of the Sun in the sky and standard clock time. Notice the faded sundial on the school wall in the foreground and the clock in the background, on the top of a modern trade center in Curitiba, Brazil. This time difference occurs because of...

Shown above amidst wavy clouds that look like they were painted by Van Gogh is a sliver of the Moon, as observed near my home in Zaragoza, Spain. Strong winds known locally as the cierzo, streaming over the Moncayo Mountains in the far background were responsible for the layered effect of the sky that fades from den...

The majority of planets discovered outside our solar system orbit close to their parent stars because these planets are the easiest to find. But to fully understand how distant planetary systems are put together, astronomers must conduct a census of all the planets around a star. So they need to look farther away from the star-from about the distance of Jupiter...

Astronomers using NASA's Hubble Space Telescope have discovered an immense cloud of hydrogen dubbed "The Behemoth" bleeding off a planet orbiting a nearby star. The enormous, comet-like feature is about 50 times the size of the parent star. The hydrogen is evaporating from a warm, Neptune-sized planet, due to extreme radiation from the star. A phenomenon this l...

Walking through the University of British Columbia Botanical Garden's Physic Garden, I happened to spot a patch of Asplenium scolopendrium gleaming in the sunshine. The light was making the dark centipede-like pattern of the mature sori stand out against its leaves. I was glad that I managed to take a photo that captured the interplay of light, sori, and green leaf that I saw on that warm summe...
