For this cover, we explore the solar system from the potentially life-giving winds on Venus to the strange liquid cycle on Saturn’s largest moon, Titan.

Learn about the shrinking of Jupiter’s Great Red Spot and how professional telescopes and amateur astronomers are monitoring the change.

Elsewhere in the issue, you’ll find out why we may need to copy the birds to explore another planet faster and in greater detail than ever before. You can also explore the anatomy and maintenance procedures of the Hubble Space Telescope and learn how it served as the backbone of modern astronomy for more than three decades.

We also have a detailed stargazing section filled with useful information on what to look for in the sky, including naked eye targets and binoculars and a deep sky challenge.

Depending on how carefully you do the calculations and how you organize them, all of the planets in the solar system could lie between Earth and the Moon. The distance between the Earth and the Moon varies as it orbits around us, as does the diameter of each of the planets – they are wider at their equators, so Saturn and Jupiter would have to be tilted sideways for this works. But imagine lining them all up, pole to pole. They would have barely slipped between us and our closest companion in space, blocking the sky with their rings and gas giant mass.

The moon is both incredibly distant and incredibly close, depending on how you think about it.

Welcome to the Stellar Beyond

They’re hot, they’re small, and they’re technically dead. Meet the stellar remnants that have a story of millions of years to tell. (Image credit: future)

When stars like our sun burn up, they shed their skin to leave behind a dead core. These stellar remnants are white dwarfs, pint-sized objects unlike any other. No bigger than Earth in diameter, they are white-hot and slowly cool as they fade over billions and trillions of years.

Eventually they will become star ghosts – mere shadows of themselves. 97% of the stars in the universe will one day turn into white dwarfs. In the far future of the cosmos, you’d be hard-pressed to find a star that burns up with the aid of fusion, when the universe is littered with stellar corpses.

In 1984, astronomer Farhad Yusef-Zadeh was observing the night sky when he spotted something quite unusual that stopped him in his tracks. He had been working on his doctorate at Columbia University, trying to understand the nature of compact sources. But with his colleague Don Chance and Professor Mark Morris of the University of California, Los Angeles, he helped identify three large arcs about 150 light-years long.
