NASA Shows Einstein Was Right: Our Sun Is Losing Mass – and Its Grip on Our Solar System

(19.01.2018)

As our sun gets older, it‘s losing mass, and so its gravitational pull becomes weaker. As a result, the orbits of all the planets in our solar system are expanding, not unlike „the waistband of a couch potato in midlife,“ according to a new NASA press statement.

A team of researchers from the Massachusetts Institute of Technology, the University of Maryland and the NASA Goddard Space Flight Center has shown that the aging sun is behaving according to Albert Einstein‘s theory of general relativity.

NASA Team Studies Middle-aged Sun by Tracking Motion of Mercury

(18.01.2018)

Like the waistband of a couch potato in midlife, the orbits of planets in our solar system are expanding. It happens because the Sun’s gravitational grip gradually weakens as our star ages and loses mass.

The Orbits Of All The Planets In Our Solar System Are Expanding As The Sun Gets Older, Study On Mercury’s Orbit Reveals

(25.01.2018)

“Mercury is the perfect test object for these experiments because it is so sensitive to the gravitational effect and activity of the Sun,” explained Antonio Genova, the lead author of the study and a MIT researcher working at NASA’s Goddard Space Flight Center.

Researchers were able to make these calculations from the data gathered by NASA’s MESSENGER spacecraft which made three ‘flybys’ of Mercury in 2008 and 2009 and orbited Mercury between March 2011 and April 2015 before it crashed into Mercury in 2015, Mail noted.

Merkur: BepiColombo macht letzte Schnappschüsse von der Erde

Darüber hinaus waren einige der Sensoren der zweiten Missionskomponente, nämlich des JAXA-Magnetosphärenorbiters (Mercury Magnetospheric Orbiter, kurz MIO), aktiviert.

MESSENGER Observations of Magnetic Flux Ropes in Mercury’s Plasma Sheet

(2014)

A superposed epoch analysis demonstrates that the magnetic structure of the flux ropes issimilar to what is observed at Earth, but the timescales are 40 times faster at Mercury.
