Lasers and Fool’s Gold Give a Glimpse Into Our Ocean’s Past The amount of pyrite in the sea floor gives us an idea of how much oxygen was in the ocean millions of years ago.

The amount of trace elements in ocean pyrite correspond to ocean oxygen concentrations at different points in geologic time.

Chasing Alien Worlds with a Flying Telescope SOFIA is the name of a telescope that flies in the stratosphere to collect data that is unimpeded by the Earth's atmosphere

The airborne Stratospheric Observatory for Infrared Astronomy (SOFIA) is a flying observatory aboard a modified Boeing 747 that takes infrared astronomy readings at approximately 41,000 feet above the Earth’s surface. It recently observed a mini-eclipse of the extrasolar planet named READ MORE

Why is the Sun Yellow? Red dwarf stars are much more common, so are we a fluke?

Jacob Haqq-Misra, Ravi Kopparapu, and Eric Wolf attempt to address this question in a recent paper titled “Why do we find ourselves around a yellow star instead of a red star?” and published in International Journal of Astrobiology.

Betting on Aliens Would you invest in the search for extraterrestrials for a chance to win big?

If intelligent aliens exist somewhere in the depths of space, then should we see signs of their technology? This question has motivated scientists involved in the search for extraterrestrial intelligence (SETI) to hunt for evidence of tell-tale signs of alien READ MORE

New Method for Detecting Signs of Life In the Universe A classic “biosignature,” or sign of life, is the presence of three gasses in a planet’s atmosphere -- oxygen, ozone, and methane.

by Marc Claire Research Scientist Detecting life on a planet beyond Earth would be one of the coolest things ever! In our paper, we talk about detecting signs of life on other planets that breathe out oxygen. While this strategy READ MORE

An Expedition to Collect Fish in Africa for a Gene Archive

by Tuuli Mäkinen University of Jyväskylä, Finland It was no ordinary fishing trip. In May 2011, Denis Tweddle, a research associate of the South African Institute for Aquatic Biodiversity (SAIAB), led an expedition to collect little-known fishes from the remote rivers READ MORE

Expedition to find rare pipefish in Queensland Australia

My research interests are centered on the evolutionary relationships among species of seahorse and pipefish in the family Syngnathidae through morphological study and DNA sequencing. This entails collecting and observing fish for study via scuba diving and photography in shallow inshore water in READ MORE

Will climate change eliminate the ice age cycle?

Long-term patterns in Earth’s climate show glacial cycles that correspond to variations in Earth’s orbital geometry and affect the overall amount of sunlight that the planet receives. Known as “Milankovitch cycles”, these variations are observed in geologic reconstructions of temperature and READ MORE
