More from Light from Space
Many things have been said about the Andromeda Galaxy, arguably the most majestic galaxy that amateur astronomers can image due to it's sheer size in the sky—many times larger than the Moon appears to us, but also many times dimmer. With the naked eye, even in
A rarely imaged target as it is very dim. This image took me over 50h of total exposure time. Total exposure time: 52h 40' Image resolution: 4,490 × 4,552px (0.96″/px) Shot from my driveway near Tucson, AZ in late 2023 Telescope: William Optics RedCat
Next to the Orion Nebula, the Rosette Nebula is definitely a must-do on the list of every aspiring astrophotographer. Located not too far from Orion in Monoceros, this large H II region has spectacular features, centered around a star cluster. Click or tap to enlarge/double-tap to zoom My image
A spectacular emission Nebula, the Heart Nebula is one of the classics of Northern Hemisphere amateury astronomy. In the gallery below, I've highlighted 3 very different areas of the image: Left: Planetary Nebula WeBo-1 Middle: Melotte 15 in the... heart of the Heart Nebula Right: The “Fish

I’m an Australian father of four, living in the US. Something of a corner case. Nevertheless, getting my kids Australian citizenship by descent, and then Australian passports so we can fly home legally, has kicked off a carnival of errors with a very dark side. Australia is generally thought of as a developed western liberal country with relatively high state capacity. And I have generally found that at least state government services, now administered through centralized offices, have become more efficient over time. Passport applications for children living overseas, however, remain a time machine with a difficult security overhang. Australian …
Researchers created a dataset of photos of thousands of paper-thin slices of a male and female cadaver to create one of the most detailed datasets about the human body.
In a remote corner of the driest state in the country, Anne Heggli's team has been keeping watch over some of Earth’s oldest beings. Since 02012, Heggli’s NevCAN network has recorded conditions at the Nevada Bristlecone Preserve every eight minutes. The result is more than 120 million data points and a high-resolution portrait of how a bristlecone pine thrives. Paleoclimatologist Adam Csank showed how bristlecone microcores reveal the droughts and floods these trees survived long before us, a history that fine-tunes models of what's ahead. Artist and philosopher Jonathon Keats went further. “The most accurate clock,” he said, “is a tree.” His monumental artwork Centuries of the Bristlecone keeps bristlecone time, a clock calibrated to the trees' own growth over millennia. Together, Heggli, Keats and Csank made the case for long science: patient, continuous observation that will help us answer future urgent questions. “Data at this resolution,” Csank said, “is like a Rosetta Stone” for understanding nature’s resilience. At fourteen years young, the bristlecone record is just beginning, Heggli said, but it already holds the key to questions like these: How will bristlecones adapt? What happens when the droughts and floods they've weathered for millennia arrive faster and more frequently? “We can't answer the questions if we're not watching,” said Csank. “We are the stewards of this data,” Heggli concluded. “This is why we need long science.”
