A team of U.S. and German astrophysicists have made the first ever detection of X-rays coming from a comet. ... Following the initial detection, the team reported repeated X-ray emissions from the comet over the next 24 hours. ... One preliminary theory is that X-ray emission from the Sun was absorbed by a cloud of gaseous water molecules surrounding the nucleus of the comet, and then were re-emitted by the molecules in a process physicists call "fluorescence." ... Comets . ...

Detected Supernovae . The search have produced till now the detections of 4 SNe. ... This result highlights the power of infrared monitoring in detecting Obscured SNe and indicates that optical surveys are probably missing a significant fraction of SNe, especially in obscured systems such as starburst galaxies. ... In Fig. we show the archival SOFI image of NGC3256 (left) and the first image obtained in 2001 (right) where SN2001db has been detected. ...

... 2014 July 21 . Spacecraft Rosetta Shows Comet has Two Components . Image Credit: ESA / Rosetta /MPS for OSIRIS Team ; MPS /UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA . Explanation: Why does this comet's nucleus have two components? The surprising discovery that Comet 67P/Churyumov–Gerasimenko has a double nucleus came late last week as ESA 's robotic interplanetary spacecraft Rosetta continued its approach toward the ancient comet's core. ...

... Discovering and explaining an effect of enhancing the fracture toughness of metal matrix composites as a result of reinforcing the matrix with brittle fibres (1975). Discovering and explaining a synergetic effect in composites with metal matrix and oxide fibres (2000). Predicating a possibility of formation of non- brittle single crystalline fibres and realization of the possibility (2000). Discovery a new w ay to organize non- brittle structures composed of brittle components. ...

... On the base of laboratory simulations (on rotating shallow water) of the formation of spiral arms in galactic gaseous disks, the existence of giant anticyclones in them was predicted. Numerical simulations shown that the vortex structures arise on a linear stage of spiral arms formation simultaneously with the latter. ... Thus second giants structures, after spiral arms, in spiral galactic disks are discovered. ...

Peremennye Zvezdy ( Variable Stars ) 28 , No. ... I present the discovery of a pulsating component in light variations of the known eclipsing binary NSV 10993 based on the NSVS and ASAS-3 publicly available data. ... I re-analysed the NSVS and ASAS-3 data (NSVS 10974803, NSVS 11094130, and ASAS 183213+1217.1) using the WINEFK package by Dr. V.P. Goranskij and found pulsations superposing the eclipsing light curve. ... The eclipsing light curve is similar to the EB-type curves. ...

Here we report our discovery of a band of blue luminescence (BL) in the Red Rectangle nebula. ... The spectrum of this newly discovered BL is most likely fluorescence from small neutral polycyclic aromatic hydrocarbon (PAH) molecules. ... If the carriers of this near-UV/blue fluorescence are PAHs, they are most likely neutral PAH molecules consisting of three to four aromatic rings such as anthracene (C14H10) and pyrene (C16H10). ...
