Today, we take a look at three recent papers attempting to explain various phenomena on Mars. One uncovers the cause of discrete aurorae. Another explains the martian haze. And a third actually ends up with more questions than answers. Plus, Boeing’s OFT-2 returns to Earth, ESA’s Solar Orbiter makes its...

Due to the gravitational pull of Jupiter on the fragments and dust of comet 73P/Schwassmann-Wachmann, Earth’s orbit may be moving through a dense portion of the comet’s trail on May 31. This alignment could result in an unusually spectacular meteor outburst, and we’ll interview astronomer Pierre Martin about this...

Researchers using radioactive decay analysis have recreated the early history of some asteroids in our solar system, revealing a more chaotic phase than previously thought. Plus, a near-Earth asteroid, a solar sail, a trove of black holes, and this week in rocket history, we look back at Mercury-Atlas 7.

Fast, strong magnetic winds caused by quickly rotating pulsars may be accelerating particles like electrons to extremely high-energy states and creating gamma-ray photons in their wake. Plus, missions close to home, large and distant objects, some pretty Hubble photos, and laser simulations of fast radio bursts.

Over the past three decades, astronomers around the world have been using the observations of the Hubble Space Telescope to more precisely calculate the expansion of the universe. And they have converged on a precision of just over 1%. Plus, Boeing launches Starliner, Voyager 1 struggles, and Erik reviews his...
