... Luminous blue variable (LBV) stars are the most massive stars with 40-120 solar masses, which are passing the short stage of evolution losing their hydrogen envelopes before exploding as Supernovae. These are extremely rare objects, only about a dozen of the most massive LBVs are known in the Galaxy. ... In the spectral observations of stars with infrared circular nebulae, found in the Spitzer survey (24 microns), a new LBV star in the Galaxy was discovered. It was named MN112. ...

Estimating the NEO Population and Impact Risk: Past, Present and Future . ... Since most of the risk resides in the largest impactors, finding that fraction of the largest bodies, and that none of them has a significant chance of impacting in the next century or so, "retires" more than 90 % of the impact risk, including most of the risk of a globally catastrophic impact event. ... In the mid-size range, from ~150 m to ~1 km, the main risk is from tsunami generated by an ocean impact. ...

... The SN 1998bv discovered on April 6, 1998 in the blue compact galaxy HS 1035+4758 is the second supernova observed in a low-mass galaxy with intense SF burst. ... According to its characteristic spectrum, SN 1998bv is a type II supernova with estimated peak absolute brightness M 16.3. The very slow fading of its brightness suggests that the SN was discovered at the Plateau phase, 20-30 days after the peak of the light curve. The most probable classification of SN 1998bv is regular SN II-P. 3. ...
