Natural radio signal buzzes in Venusâ atmosphere
New measurements from Parker Solar Probe – the first new direct measurements of Venus’ atmosphere in nearly 30 years – showed an unexpected natural radio signal being emitted by Venus’ ionosphere. The probe made the discovery while using Venus as a “gravity slingshot” to come closer to the sun.
How do you measure the mass of a star?
Binary stars – a star system consisting of two stars – are extremely useful. They give all the information needed to measure the stars masses’. Here is how.
Biodiversity loss in warming oceans | Stanford News – Stanford University News
A fossil study from Stanford University suggests the diversity of life in the world’s oceans declined time and again over the past 145 million years during periods of extreme warming. Many other factors are also expected to negatively impact habitat…

Spica, bright beacon of Virgo, is a whirling pair of egg-shaped stars
Spica, the brightest star in Virgo, is a very close, scorching-hot pair of stars, whirling around one another. One may go supernova as it nears the end of its lifetime.
NASA expects upcoming space telescope to find 100,000 new worlds
NASA’s Roman space telescope mission – launching sometime in the mid-2020s – is expected to find at least 100,000 new exoplanets orbiting other stars, say astronomers.
Catastrophic sea-level rise from Antarctic melting possible with severe global warming – EurekAlert
The Antarctic ice sheet is much less likely to become unstable and cause dramatic sea-level rise in upcoming centuries if the world follows policies that keep global warming below a key 2015 Paris climate agreement target, according to a Rutgers…
Catastrophic Sea-Level Rise from Antarctic Melting is Possible with Severe Global Warming – Rutgers Today
Antarctic ice sheet is more likely to remain stable if Paris climate agreement is met If Paris Agreement targets are not met, the collapse of melting Antarctic ice shelves – like the Wilkins Ice Shelf in 2009 – could cause…
Map of Milky Way halo reveals dark matter ocean
The gravity of the Large Magellanic Cloud – one of the Milky Way’s satellite dwarf galaxies – is collecting stars behind it in a trail, like the wake from a boat, as it travels through our galaxy’s halo.
Revealed: Al Gore’s Real Climate Catastrophe
Next month is the thirtieth anniversary of the most entertaining and damning chapter in Al Gore’s career. By the mid-nineteenth century, our knowledge of atmospheric chemistry was sufficiently advanced for a few sharp minds to ponder whether an increase in…
