We bring you, as usual, the Sun and Moon and stars, plus some galaxies and a new section on astrobiology. Some highlights are short (the newly identified class of gamma‐ray bursts, and the Deep Impact on Comet 9P/Tempel 1), some long (the age of the universe, which will be found to have the Earth at its center), and a few metonymic, for instance the term “down‐sizing” to describe the evolution of star formation rates with redshift. 

Cosmic rays: a review for astrobiologists.

This work focuses on the astrobiological aspects of cosmic rays with regard to the enormous amount of new data available, some of which may, in fact, improve knowledge about the radiation of cosmic origin on Earth.

Parallaxes and proper motions for 20 open clusters as based on the new Hipparcos catalogue

Context. A new reduction of the astrometric data as produced by the Hipparcos mission has been published, claiming that the accuracies for nearly all stars brighter than magnitude Hp = 8 are

Twenty-five years of helioseismology research in Uzbekistan

The Ulugh Beg Astronomical Institute was involved in the IRIS helioseismology project from the mid-1980s through to the end of the project in 2001. This project aimed to study the deep interior of

Growth, distribution and physiochemical properties of wax apple (Syzygium samarangense): A Review

It can be concluded that GA3, NAA, 2,4-D, H2O2 and girdling have significant effect on fruit growth, development and yield improvement and Fruit pigmentations and anthocyanin content also significantly by using these growth promoting chemicals and girdsling technique.

Usage bibliometrics

The state-of-the-art in usage-based informetric, i.e. the use of usage data to study the scholarly process, is reviewed.

Some of the principal facts which any cosmological theory will have to account for are pointed out and a new effect of masses upon light will be suggested which is a sort of gravitational analogue of the Compton effect.

The state of the Universe

The past 20 years have seen dramatic advances in cosmology, mostly driven by observations from new telescopes and detectors, but the emerging ‘standard’ model leaves many details of galaxy formation still to be worked out.

The Emergence of the Thick Disk in a Cold Dark Matter Universe

The disk galaxy simulated using our chemodynamic galaxy formation code, GCD+, is shown to have a thick-disk component. This is evidenced by the velocity dispersion versus age relation for solar

Astrophysical parameters of Galactic open clusters

We present a catalogue of astrophysical data for 520 Galactic open clusters. These are the clusters for which at least three most probable members (18 on average) could be identified in the ASCC-2.5,

Cosmic Star Formation, Reionization, and Constraints on Global Chemical Evolution

Motivated by the Wilkinson Microwave Anisotropy Probe (WMAP) results indicating an early epoch of reionization, we consider alternative cosmic star formation models that are capable of reionizing the

A Stellar Swan-Song

New stellar evolution calculations can explain the extremely rapid transformation of the star, which has started to heat up and contract again, only ~10 years after it first swelled up to gigantic proportions.

Stars within 15 Parsecs: Abundances for a Northern Sample

We present an abundance analysis for stars within 15 pc of the Sun located north of -30° declination. We have limited our abundance sample to absolute magnitudes brighter than +7.5 and have

Molecular Gas at High Redshift: Jet-induced Star Formation?

We present an alternative interpretation of the observations of BR 1202-0725 at z = 4.695 and show that its properties are consistent with a relativistic jet issuing from the quasar core, propagating

Infrared radiation from an extrasolar planet

A class of extrasolar giant planets—the so-called ‘hot Jupiters’ (ref. 1)—orbit within 0.05 au of their primary stars (1 au is the Sun–Earth distance). These planets should be hot and so emit

Light and Motion in the Local Volume

Using high-quality data on 149 galaxies within 10 Mpc, I find no correlation between luminosity and peculiar velocity at all. There is no unequivocal sign on scales of 1-2 Mpc of the expected
