Research Breaks the Warp Barrier for Faster-than-Light Travel

If travel to distant stars within an individual's lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about superluminal (faster-than-light) transport based on Einstein's theory of general relativity would require vast amounts of hypothetical particles and states of matter that have "exotic" physical properties such as negative energy density.

Curtin University-Led Global Fireball Observatory Makes Rare Find

Curtin University has played a major role in the recovery of a rare meteorite in the UK, made possible by dedicated fireball observatories set up as part of the Curtin-led Global Fireball Observatory (GFO).

Most Distant Cosmic Jet Provides Valuable Information About the Early Universe

Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) and Very Long Baseline Array (VLBA) have found and studied the most distant cosmic jet discovered so far -- a jet of material propelled to nearly the speed of light by the supermassive black hole in a quasar some 13 billion light-years from Earth.

New Measure of Hubble Constant Reveals Mismatch Between Estimates of the Cosmic Fate

Determining how rapidly the universe is expanding is key to understanding our cosmic fate, but with more precise data has come a conundrum: Estimates based on measurements within our local universe don't agree with extrapolations from the era shortly after the Big Bang 13.8 billion years ago.

Study Advances a Decisive Test to Investigate the Origin of Solar-Mass Black Holes

What is the origin of black holes and how is that question connected with another mystery, the nature of dark matter- Dark matter comprises the majority of matter in the Universe, but its nature remains unknown.

Astronomers Discover a "Radio-Loud" Quasar

With the help of the European Southern Observatory's Very Large Telescope (ESO's VLT), astronomers have discovered and studied in detail the most distant source of radio emission known to date. The source is a "radio-loud" quasar -- a bright object with powerful jets emitting at radio wavelengths -- that is so far away its light has taken 13 billion years to reach us. The discovery could provide important clues to help astronomers understand the early Universe.

MAROON-X on Gemini North Helps Measure Properties of Transiting Exoplanet

Astronomers using the recently installed instrument MAROON-X on Gemini North have determined the mass of a transiting exoplanet orbiting the nearby star Gliese 486. As well as putting the innovative new instrument through its paces, this result, when combined with data from the TESS satellite, precisely measures key properties of a rocky planet that is ideal for follow-up observations with the next generation of ground- and space-based telescopes.
