The disks of dust and gas that surround young stars are the formation sites of planets. New images from thAtacama Large Millimeter/submillimeter Array (ALMA) reveal never-before-seen detai...
Some Sun-like stars are ‘Earth-eaters.’ During their development they ingest large amounts of the rocky material from which ‘terrestrial’ planets like Earth, Mars and Venus are made.
In a previous study published in Astrobiology, we focused on the evolution of habitability of a 10 M_E super-Earth planet orbiting a star akin to the Sun. This study was based on a concept of planetar...
Magnetic turbulence is found in most space plasmas, including the geospace environment. Recent spacecraft observations of magnetic turbulence in the ion foreshock, in the magnetosheath, in the polar ...
The Indian team at ISRO has been part of the Whole Earth Telescope (WET) team since 1988 when we first participated in the campaign on V471 Tau.We have been part of many other observing campaigns o...
This paper reviews the precision of the measurements of the Earth rotation fluctuations realized during the last decades; particularly the observations performed during the last ten years allow to c...
The variations of universal times difference UT1-TAI and Earth’s rotation instantaneous pˆole coordinates (X,Y) are studied in the frequency range of 3 - 8 yr−1 as a function of the solar...
It is shown that Five Year Oscillation in Earth rotation is possibly caused by variable solar UV radiation and a corresponding perturbation mechanism is suggested.
In this paper we examine air densities derived from our realiza- tion of aeronomic atmosphere models based on accelerometer measurements from satellites in a low Earth's orbit (LEO). Using the adapt...
April 25, 2007,A giant red orb in the sky shines down on planet Gliese 581c during the day, and at night the bright lights of two neighboring planets move gently through the starry skies. On the surfa...
Reviving a calculation made by Eddington in the 1920s, and using the most recent and comprehensive databases available on stars and galaxies, including more than 2,500,000 stars and around 20,000 gala...
