Parker Solar Probe will explore the corona, a region of the Sun only seen from Earth when the Moon blocks out the Sun's bright face during total solar eclipses. The corona holds the answers to many o ...
Effect of a prograde, parabolic fly-by of a star with a) M=0.5 M , b) M2= 1, M and c) M2= 5 M that is inclined by 60 degrees and has an angle of periastron equal zero. The perihelion distance is alwa ...
Instant of a simulation in which two black holes merge. The collision of two rotating wormholes would trigger a similar deformation of space-time, leaving 'echoes' in the signal. Credit: LIGO LabCalt ...
When a particle with a certain angular momentum is located at the critical distance rst, it remains at rest while the spacetime is rotating around it. The closer a particle is to this critical distan ...
Within ancient rocks in Arizona's Petrified Forest National Park, scientists have identified signs of a regular variation in Earth's orbit that influences climate. Here, one of the authors near the r ...
