The Mysterious History of a Black Hole Has Been Decoded by Scientists : ScienceAlert
One of the common misconceptions about black holes is that they devour not only matter, but also the history of that matter. So when a black hole forms, you can only guess how it came to be.
That isn’t entirely true.
Informational history…

I-band Asymptotic Giant Branch (IAGB) Stars. II. A First Estimate of Their Precision and a Differential Zero Point*
Hubble Space Telescope observations of 92 galaxies that have a strong showing of I-band asymptotic giant branch (IAGB) stars in their color–magnitude diagrams (CMDs) are used to measure the relative offset between the mean apparent I-band…

Is Venus Alive? A Churning Crust Could Be Powering Its 85,000 Volcanoes
Venus may be far more geologically alive than anyone expected. New research suggests its outer crust could be churning with convection, a process that helps move heat and may explain the planet’s tens of thousands of volcanoes. This overturns…

Startups demonstrate in-orbit satellite autonomy
A small spacecraft earlier this year successfully demonstrated edge autonomy — or the capability of a satellite to analyze data and make decisions independently without waiting for instructions from ground control.
The demonstration…
