Astronomers uncover evidence that there could be many more Earth-sized planets than previously thought

Some exoplanet searches could be missing nearly half of the Earth-sized planets around other stars. New findings from a team using the international Gemini Observatory and the WIYN 3.5-meter Telescope…

‘WTF?’: newly discovered ghostly circles in the sky can’t be explained by current theories, and astronomers are excited

'WTF?': newly discovered ghostly circles in the sky can't be explained by current theories, and astronomers are excited In September 2019, my colleague Anna Kapinska gave a presentation showing interesting…

This image shows a comparison of the new image (top) of the western wall of the Carina Nebula taken by the international Gemini Observatory, a Program of NSF’s NOIRLab, and an image of the same region without Adaptive Optics (bottom). The top image was taken with the Gemini South telescope with the GSAOI instrument using the GeMS adaptive optics system, and the bottom image was taken at the Cerro Tololo Inter-American Observatory with the Víctor M. Blanco 4-meter Telescope using the NEWFIRM instrument.

Comparison of images with and without Adaptive Optics

Adaptive optics control the surfaces of a telescope's optic - often the main mirror - to take into account the turbulence in the Earth's atmosphere. By doing this, the distortion…
