The Milky Way Galaxy Has A Clumpy Halo

The Milky Way galaxy is in the recycling business.

In a surprising discovery, astronomers using two Maunakea Observatories - W. M. Keck Observatory and Canada-France-Hawaii Telescope (CFHT) - have found a globular star cluster in the Andromeda Galaxy that contains a record-breaking low amount of metals.

The Ghost Nebula

The brightest stars embedded in nebulae throughout our galaxy pour out a torrent of radiation that eats into vast clouds of hydrogen gas - the raw material for building new stars.

Quasars are the brightest objects in the universe and among the most energetic.

At present, the formation of galaxies is difficult to understand without the presence of a ubiquitous, but mysterious component, termed dark matter.

A team of astronomers at the University of Hawaii at Manoa Institute for Astronomy (IfA) has produced the world's largest three-dimensional astronomical imaging catalog of stars, galaxies and quasars.

Stars And Planets May Be Siblings

An international team of scientists has discovered planet formation in a star system younger than 500,000 years old.

Shedding Light On Star Formation

Astronomers from The University of Western Australia's node of the International Centre for Radio Astronomy Research (ICRAR) have developed a new way to study star formation in galaxies from the dawn of time to today.

Gemini South Views The Carina Nebula

NASA's James Webb Space Telescope is still more than a year from launching, but the Gemini South telescope in Chile has provided astronomers a glimpse of what the orbiting observatory should deliver.

Lithium is an ancient element that is almost as old as the universe itself. As one of the building blocks of our present-day universe though, the context of lithium observed in many celestial bodies often disaccord with predictions of classic theories.

When a star unleashes as much energy in a matter of days as our Sun does in several billion years, you know it's not going to remain visible for long.

Hubble View Of Spiral Galaxy NGC 5643

This stunning image by the NASA/ESA Hubble Space Telescope features the spiral galaxy NGC 5643 in the constellation of Lupus (the Wolf).

A study of comet motions indicates that the Solar System has a second alignment plane.

It was found using observations made with the Gran Telescopio Canarias (GTC), at the Roque de los Muchachos Observatory, (GarafĂ­a, La Palma, Canary Islands), and with the ATACAMA Large Millimetre/submillimetre Array (ALMA), in Chile.

How Disk Galaxies Evolve Smoothly

Computer simulations are showing astrophysicists how massive clumps of gas within galaxies scatter some stars from their orbits, eventually creating the smooth, exponential fade in the brightness of many galaxy disks.

Astronomers present an explanation for the mesmerising shapes of planetary nebulae. The discovery is based on an extraordinary set of observations of stellar winds around ageing stars.

An international team of astronomers using NASA's Transiting Exoplanet Survey Satellite (TESS) and retired Spitzer Space Telescope has reported what may be the first intact planet found closely orbiting a white dwarf, the dense leftover of a Sun-like star, only 40% larger than Earth.

With almost two decades of mid-infrared (IR) imaging from the largest observatories around the world including the Subaru Telescope, a team of astronomers was able to capture the spiral motion of newly formed dust streaming from the massive and evolved binary star system Wolf-Rayet (WR) 112.

Hubble Views Globular Cluster NGC 1805

Many colorful stars are packed close together in this image of the globular cluster NGC 1805, taken by the NASA/ESA Hubble Space Telescope.

The "IceCube" neutrino observatory deep in the ice of the South Pole has already brought spectacular new insights into cosmic incidents of extremely high energies.
