Penny Sackett
Penny Diane Sackett (born 28 February 1956) 19 pages. is an American-born Australian astronomer and former director of the Research School of Astronomy and Astrophysics (RSAA) at the Australian National University (ANU). Professor Sackett was the Chief Scientist of Australia from November 2008 until March 2011. Early life and studies Born in Lincoln, Nebraska – the daughter of an accountant and a business machine technician – Sackett spent her childhood in Omaha. She was interested in science from a very young age, and her original inclination was towards biology and medicine. While initially unenthusiastic about physics, Sackett developed a passion for the discipline through being mentored by her high school physics teacher. Her undergraduate study was at University of Nebraska at Omaha, graduating ''summa cum laude'' in 1978. In 1984, she completed her PhD in theoretical physics at the University of Pittsburgh. Her thesis title is ''Scale Parameters for Finite Temperature A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Stromlo Observatory
Mount Stromlo Observatory located in the west of Canberra, Australia, is part of the Research School of Astronomy and Astrophysics at the Australian National University (ANU). Australia's oldest telescope and several others at the observatory were destroyed by bushfire in 2003. History The observatory was established in 1924 as The Commonwealth Solar Observatory. The Mount Stromlo site had already been used for observations in the previous decade, a small observatory being established there by Pietro Baracchi using the Oddie telescope located there in 1911. The dome built to house the Oddie telescope was the first Commonwealth building constructed in the newly established Australian Capital Territory. In 1911 a delegation for an Australian Solar Observatory went to London seeking Commonwealth assistance. The League of the Empire sought subscriptions to assist raising funds. Survey work to determine the site's suitability had begun as soon as the idea of a new Capital was establi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OGLE-2005-BLG-390Lb
OGLE-2005-BLG-390Lb (known sometimes as Hoth by NASA) is a super-Earth ice exoplanet orbiting OGLE-2005-BLG-390L, a star from Earth near the center of the Milky Way, making it one of the most distant planets known. On January 25, 2006, Probing Lensing Anomalies NETwork/ Robotic Telescope Network (PLANET/Robonet), Optical Gravitational Lensing Experiment (OGLE), and Microlensing Observations in Astrophysics (MOA) made a joint announcement of the discovery. The planet does not appear to meet conditions presumed necessary to support life. Characteristics Mass, radius and temperature The planet is estimated to be about five times Earth's mass (5.5 ). Some astronomers have speculated that it may have a rocky core like Earth, with a thin atmosphere. Its distance from the star, and the star's relatively low temperature, means that the planet's likely surface temperature is around , making it one of the coldest known. If it is a rocky world, this temperature would make it likely th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dark Matter
In astronomy, dark matter is an invisible and hypothetical form of matter that does not interact with light or other electromagnetic radiation. Dark matter is implied by gravity, gravitational effects that cannot be explained by general relativity unless more matter is present than can be observed. Such effects occur in the context of Galaxy formation and evolution, formation and evolution of galaxies, gravitational lensing, the observable universe's current structure, mass position in galactic collisions, the motion of galaxies within galaxy clusters, and cosmic microwave background Anisotropy, anisotropies. Dark matter is thought to serve as gravitational scaffolding for cosmic structures. After the Big Bang, dark matter clumped into blobs along narrow filaments with superclusters of galaxies forming a cosmic web at scales on which entire galaxies appear like tiny particles. In the standard Lambda-CDM model of cosmology, the mass–energy equivalence, mass–energy content o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravitational Microlensing
Gravitational microlensing is an astronomical phenomenon caused by the gravitational lens effect. It can be used to detect objects that range from the mass of a planet to the mass of a star, regardless of the light they emit. Typically, astronomers can only detect bright objects that emit much light (stars) or large objects that block background light (clouds of gas and dust). These objects make up only a minor portion of the mass of a galaxy. Microlensing allows the study of objects that emit little or no light. When a distant star or quasar gets sufficiently aligned with a massive compact foreground object, the bending of light due to its gravitational field, as discussed by Albert Einstein in 1915, leads to two distorted images (generally unresolved), resulting in an observable magnification. The time-scale of the transient brightening depends on the mass of the foreground object as well as on the relative proper motion between the background 'source' and the foreground 'l ...

Extrasolar Planet
An exoplanet or extrasolar planet is a planet outside the Solar System. The first confirmed detection of an exoplanet was in 1992 around a pulsar, and the first detection around a main-sequence star was in 1995. A different planet, first detected in 1988, was confirmed in 2003. In 2016, it was recognized that the first possible evidence of an exoplanet had been noted in 1917. In collaboration with ground-based and other space-based observatories the James Webb Space Telescope (JWST) is expected to give more insight into exoplanet traits, such as their Extraterrestrial atmosphere, composition, Natural environment, environmental conditions, and Extraterrestrial life, potential for life. There are many methods of detecting exoplanets. Astronomical transit, Transit photometry and Doppler spectroscopy have found the most, but these methods suffer from a clear observational bias favoring the detection of planets near the star; thus, 85% of the exoplanets detected are inside the tida ...

Kim Carr
Kim John Carr (born 2 July 1955) is an Australian former politician who served as a Senator for Victoria between 1993 and 2022. Representing the Labor Party, he was a minister in the Rudd and Gillard governments. Carr is a graduate of the University of Melbourne, and before entering politics worked as a schoolteacher and political staffer. He was appointed to the Senate in 1993, filling a casual vacancy, and was made a member of the shadow ministry after Labor's defeat at the 1996 election. Carr held a variety of portfolios in the Labor governments between 2007 and 2013. He was considered a leader of the Labor Left faction in Victoria until 2016 when he formed the Industrial Left, a breakaway mini-faction comprising nearly all of Carr's union allies. He became the most senior senator and thus father of the senate in 2019, retaining the title until his retirement in 2022. Early life Carr was born on 2 July 1955 in Tumut, New South Wales.

2003 Canberra Bushfires
The 2003 Canberra bushfires caused severe damage to the suburbs and outer areas of Canberra, the capital city of Australia, during 18–22 January 2003. Almost 70% of the Australian Capital Territory's (ACT) pastures, pine plantations, and nature parks were severely damaged, and most of the Mount Stromlo Observatory was destroyed. After burning for a week around the edges of the ACT, the fires entered the suburbs of Canberra on 18 January 2003. Over the next ten hours, four people died, over 490 were injured, and 470 homes were destroyed or severely damaged, requiring a significant relief and reconstruction effort. Buildup to the event On 8 January 2003, lightning strikes started four fires in New South Wales, over the border but in close proximity to Canberra. Despite their proximity and very small initial sizes, low intensity, and low rate of spread, these fires were not extinguished or contained by New South Wales emergency services personnel.
