Earth as a planet

From the editor: As the extraordinary pace of astronomical discovery carries on, we increasingly see that the stuff of life is spread throughout the cosmos. Life, even complex life, must be common out there. We know of several hundred billion stars in our galaxy, at least 100 billion galaxies, and planets around most of theContinue reading “Earth as a planet” The post Earth as a planet appeared first on Astronomy Magazine.

Solving the climate equation

My childhood fascination with the night sky led me to study astronomy and physics at university. By my second year, I was operating the telescope atop the physics building, tracking celestial objects — just like astronomy student Kate Dibiasky in the disaster movie Don’t Look Up.I never imagined I’d also soon find myself alerting othersContinue reading “Solving the climate equation” The post Solving the climate equation appeared first on Astronomy Magazine.

How to build climate solutions: An interview with Tony Fadell

In many ways, Tony Fadell built the digital world we live in. At the turn of the millennium, his efforts to build a pocket-sized, hard-disk-based device that could hold 1,000 songs in MP3 format caught the attention of Apple. Within months, he had been hired by the firm, and less than a year after hisContinue reading “How to build climate solutions: An interview with Tony Fadell” The post How to build climate solutions: An interview with Tony Fadell appeared first on Astronomy Magazine.

Why our climate future depends on Antarctica

In January 1774, Captain James Cook’s third and final attempt to sail south in search of the elusive Terra Australis was blocked by impenetrable sea ice. A frustrated Cook left the question of a southern land mass unanswered and later wrote, “If any one should have resolution and perseverance to clear up this point byContinue reading “Why our climate future depends on Antarctica” The post Why our climate future depends on Antarctica appeared first on Astronomy Magazine.

How we study our planet

Astronomy magazine tends to focus on space observatories that peer beyond Earth, into the depths of space. But the vast majority of observational satellites around our blue world stare right back at us. From weather to climate to ocean currents to vegetation, all kinds of Earth-sensing satellites surround our planet, giving a bird’s-eye view ofContinue reading “How we study our planet” The post How we study our planet appeared first on Astronomy Magazine.

April 2025: What’s in the Southern Hemisphere sky this month?

Face north after darkness falls and the prominent constellations Taurus, Orion, Canis Major, and Gemini will grab your attention. Mars resides in the last of these star groups during April’s first half. The magnitude 0.4 planet starts the month 4° south of Gemini’s luminary, 1st-magnitude Pollux. Mars’ eastward motion relative to the background stars carriesContinue reading “April 2025: What’s in the Southern Hemisphere sky this month?” The post April 2025: What’s in the Southern Hemisphere sky this month? appeared first on Astronomy Magazine.

April 2025: What’s in the sky this month? Jupiter and Mars remain prominent, while Venus, Mercury, and Saturn rule the morning skies

The planets offer exciting views in April. Jupiter is a brilliant object in the evening sky, although the observing window narrows as the Sun sets later each day. Mars is past its best, but remains bright and high in the sky. Mercury, Venus, and Saturn make an early-morning appearance before sunrise. And a special treatContinue reading “April 2025: What’s in the sky this month?
