... We present a photometric and spectroscopic study of the unique isolated nearby galaxy KKR25. The isolated dwarf spheroidal (dSph) galaxy KKR25 was discovered by Karachentseva, Karachentsev Richter (1999, A , 135, 221) during the search of dwarf galaxies in the direction of the Local Void. In spite of its isolation KKR 25 has no gas and looks like a normal dwarf spheroidal system. ... This is the first known planetary nebula in a dwarf spheroidal galaxy outside the Local Group. ...

In this scenario, small dark-matter haloes are expected to form first and later merge and accrete onto larger haloes to form more massive galaxies like the Milky Way. ... Our Milky Way is surrounded by a vast population of gas clouds, called high-velocity clouds (HVCs), that are mainly detectable in H i emission. ... Compact high-velocity clouds around the Milky Way . ...

... The highly obscured cases in our sample are generally the bright, central regions of galaxies with high overall attenuation but are not otherwise remarkable. ... The small fraction of highly obscured regions seen in this sample of normal, star-forming galaxies suggests that on 500 pc scales the timescale for significant dispersal or breakup of nearby, optically thick dust clouds is short relative to the lifetime of a typical star-forming region. ...

One way to find this out it to look for glowing hydrogen , a material common to hot star-forming regions . To find large areas of glowing hydrogen , the Hubble Space Telescope 's NICMOS instrument surveyed about 100 nearby spiral galaxies . Six of these galaxies are shown above: NGC 5653, NGC 3593, NGC 891 , NGC 6946, NGC 4826 , and NGC 2903. ... About APOD > . ...

So how do we find objects on the other side of the Universe? ... The latest instruments enable us to scan large areas of sky. Using Cerro Tololo's Blanco 4m telescope and the Canada-France-Hawaii 3.5 metre telescope , we are able to scan a piece of sky larger than the size of the moon every 5 minutes to a faintness level which allows us to find Type Ia supernovae halfway across the Universe. Type Ia supernovae are very rare - but each image we take contains 50000 galaxies. ...

... ESO . ... Galaxies . ... Now, however, Dante Minniti and Albert Zijlstra [1] , working at the ESO 3.5-metre New Technology Telescope (NTT), have found a large halo of old and metal-poor stars around one of the dwarf galaxies in the Local Group. ... This does not necessarily imply that all dwarf galaxies must likewise lack halos: it is also possible that the halos of the Magellanic Clouds were stripped away when they came too close to the Milky Way sometime in the past. ...

K-band Arcetri Obscured Supernova Search . What is the KAOSS Project? W hat is the KAOSS Project? Some recent surveys aimed at detecting Supernovae (SNe) in the optical have found that starburst galaxies do not show evidence for an enhanced SN rate, with respect to quiescent galaxies (Richmond et al. ... A similar result was obtained by Navasardyan et al. (2001) who looked for SNe in interacting galaxies, finding no evidence for correlations between SN rate and galaxy properties. ...

... A tussle in the distant Universe. This Hubble Space Telescope image shows evidence for a merger between a quasar and a companion galaxy. The quasar is the bright object just beneath the image center, and the wisps of material around it are remains of a galaxy disrupted by the interaction between it and the quasar. ...

Thirteen enthusiastic pulsarists packed into the Arecibo control room today for the first observations of the ALFA Pulsar consortium! ... The initial set of scans we obtained do not indicate any changes in pulsar period from any orbital Doppler effect, so the pulsar does not appear to be in a compact binary. Over the course of this month we will assess whether this is a young pulsar with high magnetic field or an old, recycled pulsar. ... The Pulsar-ALFA Consortium . ... Jim Cordes (Cornell), . ...

The significance of regions devoid of galaxies (black regions) for the bunching and fragmentation theories of the evolution of the Universe is discussed. ... Using the theory, a lower limit on the average density of the gas remaining in the black regions can be set, based on the finding that eight percent of gas elements are expanding in all three dimensions at the first stage of fragmentation. ...

Study of galaxies in a nearby Lynx-Cancer Void: project and first results Pustilnik S.A. and Tepliakova A.L. (SAO) Dwarf galaxies residing in the very low density environment (voids) are expected in the frame of modern cosmological CDM models to form later and to evolve more slowely in respect of their counterparts in a more typical environment. The available data on evolution of void population are rather scarce and indirect. ...

Jupiter's volcano-pocked moon Io has been found by NASA's Galileo spacecraft to have a giant iron core that takes up half its diameter, scientists report in today's issue of Science magazine. The spacecraft also has detected a large "hole" in Jupiter's magnetic field near Io, leading to speculation about whether Io possesses its own magnetic field. ... Galileo scientists also are trying to determine the cause of the hole they found in Jupiter's magnetic field when the spacecraft was closest to Io. ...
