Sylivia Earle Tells us About National Geographic Ocean | A Global Odyssey

This week on Astronomy News with The Cosmic Companion, we are delighted to be joined by one of the world’s most renowned oceanographers, Dr. Sylvia Earle. She’s here to talk to us about her new book, National Geographic Ocean | A Global Odyssey.

We’re going to get an in-depth look…

Signs of phosphine on Venus might have just been sulfur dioxide, dashing hopes for the detection of life in the atmosphere of Venus.

In September 2020, astronomers announced the possible detection of phosphine on Venus. On our own world, phosphine is mostly produced by life, and the detection of this…

Astronomers find J0313–1806 — the most distant, ancient quasar ever seen. What’s strange is that it shouldn’t exist.

J0313–1806 shows a disk of gas and dust feeding a quasar, forming jets of energy.

More than 13 billion light years from Earth, the quasar J0313–1806 radiates vast quantities of electromagnetic radiation. This body, formed just 670 million years after the Big Bang, is seen shining with…

A Mars megaflood may have shaped Gale Crater forever. This event could reveal details of ancient waterways — and maybe life — on Mars.

Mars was once a water world, much more like the Earth than it is today. New investigations of data from the Curiosity rover shows evidence of a widespread flood in the distant past. Image credit: ESO/M. Kornmesser/N. Risinger (skysurvey.org)

Long ago, when our solar system was young, Mars was a world teeming with water. …

The Blue Ring Nebula holds answers to mysteries of binaries — as well as posing a few questions of its own.

In 2004, the Galaxy Evolution Explorer, an orbiting space telescope scanning distant groups of galaxies, found a bizarre object. Among other oddities, this body appeared to be blue, despite…

Water on the Moon has been seen before in the shadows of craters. Now, water has been detected on the sunlit face of the Moon as well.

This illustration highlights the Moon’s Clavius Crater with an illustration depicting water trapped in the lunar soil there, along with an image of NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) that found sunlit lunar water. Image credit: NASA

Water is essential to the exploration of the Solar System, and this presents one of the greatest challenges to the colonization of space…

A strange glittering is spotted around the supermassive black hole in M 87 — We talk to Dr. Maciek Weilgus of Harvard University who made the discovery.

This week, we are joined by Dr. Maciek Wielgus, astronomer at Harvard University, speaking to us from Gdansk, Poland. …

The M 87 black hole, the first body of its type ever photographed by astronomers at the Earth Horizon Telescope, shows an unusual glitter…

Snapshots of the M 87* black hole obtained through imaging / geometric modeling, and the EHT array of telescopes in 2009–2017. The diameter of all rings is similar, but the location of the bright side varies. The variation of the thickness of the ring is most likely not real and results from the limited number of participating VLBI stations in earlier experiments. Image credit: © : M. Wielgus, D. Pesce & the EHT Collaboration

The first image of a black hole released in 2019 showed the body at the center of the galaxy M87 to look almost exactly as Albert…
