Sophia Nasr is a science writer for Simulation Curriculum’s free Pluto Safari app. You might guess that a small and distant world almost 40 times farther from the sun than the Earth is from the sun would not have an atmosphere, but in the case of Pluto, you’d be wrong. In fact, Pluto is a complex world, particularly when it comes to weather patterns.
At this point, it’s safe to say that we’re going to be receiving a new ‘highest resolution image ever’ of Pluto on a close to 24 hour basis. Yesterday, we got our first peek at geologic features on the dwarf planet’s surface. And today, New Horizons beamed back the best image to date of four mysterious dark splotches near Pluto’s south pole.
After a journey of over nine years, NASA’s New Horizons spacecraft is finally close enough to discern surface features on the cold, dwarf planet.
By studying bears’ months-long lethargy, scientists may have stumbled on a way to prevent astronauts’ bone loss.
Researchers in the UK have developed a computer that can scan outer space and classify galaxy types on its own, without any human help. This image recognition AI could help develop robots that can “see” better on their own, possibly helping doctors spot tumors or airport security spot firearms.
The images reveal a great deal of variation and complexity across Pluto’s surface — including the four large dark patches near the equator first spotted by New Horizons late last month. “This object is unlike any other that we have observed,” New Horizons principal investigator Alan Stern, of the Southwest Research Institute in Boulder, Colorado, said during a news briefing today (July 6). New Horizons captured the new photos last Wednesday (July 1) and Friday (July 3), shortly before suffering a glitch that sent it into a precautionary “safe mode” on Saturday (July 4).
Researchers at the European Space Agency harness the natural lensing properties of cosmic gravity to get a closer look at a black hole.

If you think asteroids are rare, it’s only because they’re so small and dark and hard to see. An eye-opening new video (above) shows what the night sky would look like if we could see the near-Earth asteroids astronomers have discovered — it’s quite a swarm.

Black holes are, by definition, impossible to see by conventional methods and are often further obscured by thick blankets of dust or gas. But that’s not an issue for NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR). It can peek through the obscuring layers and monitor the black holes via the high-energy X-rays that they emit. And, after a recent survey that spotted five previously unknown supermassive black holes in the centers of various galaxies, NASA researchers now think there could be millions of of them dotting the Universe like the holes of an intergalactic colander.
“Thanks to NuSTAR, for the first time, we have been able to clearly identify these hidden monsters that are predicted to be there, but have previously been elusive because of their surrounding cocoons of material,” said George Lansbury of Durham University in a statement. “Although we have only detected five of these hidden supermassive black holes, when we extrapolate our results across the whole universe, then the predicted numbers are huge and in agreement with what we would expect to see.” The team’s research has been accepted for publication in The Astrophysical Journal.
