The secret of planets' perihelion between Newton and Einstein

In the early 1600s, based on astronomical observations, Kepler established that the orbit described by a planet in the solar system is an ellipse, with the sun occupying one of its foci. Assuming that a planet is subject only to the gravitational attraction of the sun, Kepler's result is easily obtained mathematically in Newton's theory. But the other planets also have a gravitational attraction on the planet in question. What is the effect of their presence?

Search for heavy bosons sets new limits

Since discovering the Higgs boson in 2012, the ATLAS Collaboration at CERN has been working to understand its properties. One question in particular stands out: why does the Higgs boson have the mass that it does? Experiments have measured its mass to be around 125 GeV—yet the Standard Model implies it has much larger mass and requires a very large correction to the mathematics in order to align theory with observation, leading to the "naturalness problem."

Thermal waves observed in semiconductor materials

'There may not be a conflict after all' in expanding universe debate

Our universe is expanding, but our two main ways to measure how fast this expansion is happening have resulted in different answers. For the past decade, astrophysicists have been gradually dividing into two camps: one that believes that the difference is significant, and another that thinks it could be due to errors in measurement.

A fast-expanding Type Ia supernova exploded in NGC 474, study finds

Using ground-based facilities, astronomers from China and elsewhere have conducted extensive optical photometric and spectroscopic observations of the supernova SN 2017fgc, which exploded in the galaxy NGC 474. Results of the study, published June 23 on, indicate that this explosion is a fast-expanding Type Ia supernova.

A white dwarf living on the edge

Astronomers have discovered the smallest and most massive white dwarf ever seen. The smoldering cinder, which formed when two less massive white dwarfs merged, is heavy, "packing a mass greater than that of our Sun into a body about the size of our Moon," says Ilaria Caiazzo, the Sherman Fairchild Postdoctoral Scholar Research Associate in Theoretical Astrophysics at Caltech and lead author of the new study appearing in the July 1 issue of the journal Nature. "It may seem counterintuitive, but smaller white dwarfs happen to be more massive. This is due to the fact that white dwarfs lack the nuclear burning that keep up normal stars against their own self gravity, and their size is instead regulated by quantum mechanics."

First you see it, then you don't: scientists closer to explaining Mars methane mystery

Why do some science instruments detect the gas on the Red Planet while others don't?
