Climate cycles may explain how running water carved Mars' surface features
Climate cycles running water carved Mars surface features
2016/12/13
Dramatic climate cycles on early Mars, triggered by buildup of greenhouse gases, may be the key to understanding how liquid water left its mark on the planet's surface, according to a team of planetar...
Climate models used to explain formation of Mars valley networks
Climate models Mars valley networks
2015/11/13
The extensive valley networks on the surface of Mars were probably created by running water billions of years ago, but the source of that water is unknown. Now, a team of Penn State and NASA researche...
Wei-xiong Huang Explain Cosmic Mysteries-Black Holes Do Not Exist
stellar mass black holes
2015/5/28
1. Celestial body center temperature is proportional to cube root of stellar mass. 2. When stellar temperature exceeds boiling point of all elements, stellar density is inversely proportional to cube ...
An interesting experimental phenomenon attracted the whole world's attention. European researchers found that the neutrinos traveled faster than the speed of light, which was difficult to explain. Thi...
Can a Satellite Galaxy Merger Explain the Active Past of the Galactic Center?
Satellite Galaxy Merger Explain Active Past Galactic Center
2011/10/9
Observations of the Galactic Center (GC) have accumulated a multitude of "forensic" evidence indicating that several million years ago the center of the Milky Way galaxy was teaming with starforming a...
Can axion-like particles explain the alignments of the polarisations of light from quasars?
axion-like particles explain alignments polarisations
2011/9/30
The standard axion-like particle explanation of the observed large-scale coherent orientations of quasar polarisation vectors is ruled out by the recent measurements of vanishing of circular polarisat...
Do micro brown dwarf detections explain the galactic dark matter?
Galactic dark matter MACHOs galaxy merging microlensing cool dust temperature cirrus clouds
2010/11/15
Context. The baryonic dark matter dominating the structures of galaxies is widely considered as mysterious, but hints for it have been in fact detected in several astronomical observations at optical,...
Can past gamma-ray bursts explain both INTEGRAL and PAMELA/Fermi anomalies simultaneously?
Gamma ray bursts gamma-ray bursts
2010/3/9
Gamma-ray bursts (GRB) have been invoked to explain both the 511 keV emission from the galactic bulge and the high-energy positron excess inferred from the PAMELA and Fermi data. While independent exp...
Hotter-than-expected neutron star surfaces help explain superburst frequency
neutron stars Astrophysical nuclear physics
2007/4/16
April 13, 2007，EAST LANSING, Mich. — A new theoretical thermometer built from heavy-duty mathematics and computer code suggests that the surfaces of certain neutron stars run significantly hotter than...
