 Otkriven dosad Zemlji najsličniji planet izvan Sunčevog Sustava Koristeći mrežu teleskopa raspršenih širom svijeta, grupa astronoma otkrila je dosad Zemlji najsličniji ekstrasolarni (izvan Sunčevog Sustava) planet. U tom otkriću sudjelovala je i Dijana Dominis (Sveučilište Potsdam). Planetu treba oko 10 godina da opkruži matičnu zvijezdu, a masa mu je oko 5 puta veća od Zemljine. To je ekstraslorani planet s najmanjom dosad otkrivenom masom i vrlo vjerojatno se radi o planetu s čvrstom kamenom ili ledenom površinom. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Smallest Earth-like planet found
Using a network of telescopes scattered across the globe, a group of astronomers, including Dijana Dominis (Potsdam University), discovered a new extrasolar planet significantly more Earth-like than any other planet found so far. The planet, which is only about 5 times as massive as the Earth, circles its parent star in about 10 years. It is the least massive exoplanet around an ordinary star detected so far and most certainly has a rocky/icy surface. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Cannibalistic Milky Way
A huge but very faint structure, containing hundreds of thousands of stars spread over an area nearly 5,000 times the size of a full moon, has been discovered and mapped by astronomers of the Sloan Digital Sky Survey. This structure is likely a remnant of a colision between a much smaller dwarf galaxy and our Milky Way. The principal author of the findings is Mario Jurić, and the second author is Željko Ivezić. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

GQ Lupi b prvi je planet otkriven izravnom slikom na kojoj se vidi planet. Ovo epholano astronomsko otkriće, u kojem je sudjelovala i Ana Bedalov, rezultat je rada grupe astronoma iz Jene pod vodstvom Dr. Neuhäusera. Planet ima masu od nekoliko Jupiterovih a udaljen je 100 AJ (AJ = astronomska jedinica = udaljenost Zemlje od Sunca) od matične zvijezde GQ Lupi A, udaljene 450 svjetlosnih godina od Zemlje. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
First direct image of an extrasolar planet
All extrasolar planets discovered so far have been detected indirectly - by measuring their gravitational interaction with the parent star. GQ Lupi b is the first planet discovered by direct imaging of the planet itself. This astronomical breakthrough was achieved by a group of astronomers, including Ana Bedalov, from Jena led by Dr. Neuhäuser. The planet is several times more massive than Jupiter located at 100 AU (1 AU = astronomical unit = distance of the Earth from Sun) from its parent star GQ Lupi A, which is 450 light-years away from the Earth. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

[2004.05.19] Kako asteoridi skrivaju svoje pravo lice Ako su meteoriti porijeklom asteroidi, zašto ne pokazuju istu raspodjelu kemijskih sastava kao i asteroidi? Ovo pitanje već dugo vremena muči astronome, a odgovor možda leži u promjeni svojstava površine asteroida uslijed dugotrajnog ujtecaja svemira. Dokaz da se radi o tom procesu pronašla je grupa astronoma zajedno sa Željkom Ivezićem i Mariom Jurićem (Princeton University) koristeći mjerenja boja asteroida sa Sloan Digital Sky Survey. U svom radu objavljenom u prestižnom časopisu NATURE pokazuju kako se boja asteroida, koja je indikator kemijskog sastava površine, mijenja sa starošću asteroida. Stoga nam ne pokazuju svoj pravi kemijski sastav osim ako ne zagrebemo ispod njihove površine. A upravo takvu mogućnost pružaju nam meteoriti koji su dijelovi raspadnutih asteroida. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
How asteroids hide their true face
If meteorites originate from asteroids, why is their distribution of chemical compositions different than in asteroids? This question has been a long standing puzzle for astronomers, and the answer is maybe hidden in the changes of surface chemistry due to long exposures to space. An evidence of this process was discovered by a group of astronomers including Željko Ivezić and Mario Jurić (Princeton University). They used measurements of asteroids' colors from Sloan Digital Sky Survey to show how colors, which are indicators of surface chemistry, change with the age of asteroids. This is why asteroids do not show us their true chemical composition unless we scratch beneath their surface. Meteorites give us such an opportunity since they are debris from asteroids. Their result is presented in the journal NATURE. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

[2003.08.18] Neobično otkriće asteroida sa Zvjezdarnice Višnjan Sa Zvjezdarnice Višnjan i observatorije u španjolskoj Mallorci otkriven
još jedan asteroid od posebnog značaja zbog svoje putanje oko Sunca.
Zanimljivost leži i u tome da su ovaj puta u otkriću sudjelovala i internacionalna grupa studenta, polaznici Višnjanske Škole Astronomije, i to na neuobičajen
način: daljinski su preko Interneta upravljali i 1300 km udaljenim
robotskim teleskopom u Mallorci. Zahvaljujući simultanim promatranjima iz Višnjana i
Mallorce, uspjelo se vrlo brzo odrediti udaljenost tog asteroida i
Zemlje.

[2003.06.10, 2003.09.12] Marina Rejkuba (European Southern Observatory) pomoću promijenjivih zvijezda otkriva tajne galaksija Međunarodni tim astronoma pod vodstvom Marine Rejkube otkrio je na tisuće promijenjvih zvijezda tipa Mira u galaksiji Centaurus A. Ovo je prvi puta da su astronomi uspijeli izvesti takav opširan pregled Mira zvijezda izvan bliskog susjedstva Mliječne Staze. Budući da to otvara novu metodu proučavanja sastava i evolucije galaksija, ESO se oglasio i posebnim priopčenjem za novinare. Marina je također sudjelovala i u sličnoj studiji
bliske nam galaksije Veliki Magellanov Oblak, ali ovaj puta pomoću
promijenjivih tipa RR Lyrae. Rezultat je
objavljen u
časopisu SCIENCE i ukazuje na sličnosti u evoluciji Velikog
Magellanovog Oblaka i naše Mliječne Staze.

Marina Rejkuba (European Southern Observatory) is using variable stars to reveal the secrets of galaxiesAn international team of astronomers led by Marina Rejkuba has discovered more than 1000 bright variable stars of type Mira
in the galaxy Centaurus A. This is the first time that astronomers managed
to make such a stellar census in a galaxy outside the immediate neighborhood of our Milky Way. Since this opens a news method for studying the composition and evolution of galaxies, ESO prepared a press release
about the discovery. Marina also participated in a similar research of the
nearby galaxy Large Magellanic Cloud, but this time with the RR Lyrae type
of variables. This result is presented in the journal SCIENCE and suggests that Large Magellanic Cloud and the Milky Way share certain evolutionary similarities.
