Voyager Spacecraft Data Voyager 1 Sun's Heliosphere Team
- After a technical malfunction late last year rendered all of its subsequent readings as useless , NASA's Voyager 1 spacecraft—which has spent nearly a half-century in space—has been brought back online and is once again fully functioning. "The spacecraft has resumed gathering information about interstellar space," NASA said in a press release . Launched in 1977 and drifting some 15 billion miles away from Earth, on the outer reaches of our solar system, the satellite is both one of ... [Read More]

Star Phoenix Planet Planets Atmosphere Years
- Astronomers have discovered a planet beyond our solar system that's so cozy with its host star, its supremely puffy atmosphere should have been stripped down to bare rock billions of years ago. Yet the planet's thick air has endured its star's immense radiation for possibly billions of years, challenging conventional theories about how planets age in extreme, radiation-filled environments. A little over six times as big as Earth, the newfound "hot Neptune" orbits close enough to its star such ... [Read More]

Star Galaxy Dwarf Milky Way California San Diego Newsweek
- A jaw-droppingly fast star that is one of the oldest in the galaxy has been spotted racing across our galaxy by astronomers—who were looking for something else entirely. The scientists noticed the speedy star traveling at 1.3 million miles per hour, nearly three times the speed of our own sun, which orbits around our Milky Way galaxy at around half a million miles per hour. This rapid star, which has been named CWISE J124909+362116.0 ("J1249+36"), is moving fast enough to potentially ... [Read More]


Galaxies Holes Mass Black Holes Hole Low Mass
- It's well known that all massive galaxies like the Milky Way host supermassive black holes millions to billions of times the mass of the Sun in their centers. These galaxies and their black holes are intertwined, with the evolution of one significantly impacting the evolution of the other. But what about lower-mass galaxies, such as dwarfs? Astronomers aren't yet sure whether these galaxies follow a similar trend, hosting lower-mass black holes simply called MBHs (massive black holes) weighing ... [Read More]

Crab Ni Fe Supernova Explosion Ratio Dust
- A team of scientists used the NASA/ESA/CSA James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. With the telescope's MIRI (Mid-Infared Instrument) and NIRCam (Near-Infrared Camera), the team gathered data that are helping to clarify the Crab Nebula's history. The Crab Nebula is the result of a core-collapse supernova that was the death of a massive star. The supernova explosion itself was seen on ... [Read More]


Universe Pair Holes Quasars Years Team
- A team of astronomers has spotted the most distant merging galactic cores yet, seen as they were when the universe was less than a billion years old. The duo of active galactic centers, called quasars, is the only confirmed pair seen during the Cosmic Dawn. The two very red galaxies were spotted by a team using the Subaru telescope's Hyper Suprime-Cam at a redshift of z = 6.05 (indicating they are seen as they were over 12 billion years ago). To the average viewer, they look like nothing ... [Read More]


Field Sun's Magnetic Field Cycle Polarity Reversal
- The sun is on the verge of a significant event: a magnetic field reversal.  This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle. The shift in polarity indicates the halfway point of  solar maximum , the height of solar activity, and the beginning of the shift toward solar minimum.  The last time  the sun 's magnetic field flipped was toward the end of 2013. But what causes this switch in polarity, and is it dangerous? Let's ... [Read More]

Hubble Gyro Space Sensors Gyros Telescope
- The Hubble telescope has shifted into mode after months of technical issues − an aerospace engineering expert explains Imagine keeping a laser beam trained on a dime that's 200 miles away. Now imagine doing that continuously for 24 hours, while riding a merry-go-round. Seem difficult? Well, that's basically what the Hubble Space Telescope does. After months of technical issues, NASA announced June 4 that Hubble would shift into one-gyroscope mode . This essentially means that the ... [Read More]

Sn Ia Type Sn 2023adsy Sne 2023adsy
- Using the James Webb Space Telescope (JWST), astronomers from the Space Telescope Science Institute (STScI) have discovered a new supernova. Designated SN 2023adsy, the newfound stellar explosion is the most distant Type Ia supernova so far detected. The finding was detailed in a research paper published June 7 on the pre-print server arXiv . Supernovae (SNe) are powerful and luminous stellar explosions. They are important for the scientific community as they offer essential clues into the ... [Read More]


Holes Matter Black Holes Dark Matter Primordial Black Holes Study
- Sign up for CNN's Wonder Theory science newsletter.  . For about 50 years, the scientific community has been grappling with a substantial problem: There isn't enough visible matter in the universe. All the matter we can see — stars, planets, cosmic dust and everything in between — can't account for why the universe behaves as it does, and there must be five times as much of it around for researchers' observations to make sense, according to NASA . Scientists call that dark ... [Read More]


Neutron Stars Volodymyr Savchenko Carlo Ferrigno Galaxy Burst
- TOPICS: An international team, with the assistance of ESA satellites, and including researchers from UNIGE, has detected a massive eruption emanating from a magnetar, an extremely magnetic neutron star. As ESA's satellite INTEGRAL scanned the skies, it detected a surge of gamma-rays emanating from the nearby galaxy M82. Shortly after this observation, ESA's XMM-Newton X-ray space telescope sought any residual glow from the event but detected nothing. An international research group, with ... [Read More]

Earth's Day Earth Rotation Millholland Moon
- Once every 24 hours, Earth completes one rotation on its axis, marking one day on our planet. This reliable rotational period is what allowed humans to develop systems to tell time and what signals to humans, animals and plants when it is time to rest.  But Earth's rotation hasn't always been so consistent. In fact, a long, long time ago, Earth's day was much shorter, said Sarah Millholland , an assistant professor of physics at MIT. "The Earth has experienced days that were both shorter ...

Beta System Asteroid Dust Collision Pictoris
- In the grand cosmic theater, even asteroids have their dramatic moments. Astronomers, peering through the lens of the James Webb Space Telescope, have captured a jaw-dropping spectacle : the aftermath of a colossal asteroid collision in the Beta Pictoris star system. Beta Pictoris star system Beta Pictoris, a relatively young star system a mere 63 light-years away from Earth, is a captivating subject for astronomers due to its ongoing planetary formation. The system is teeming with activity, as ... [Read More]


Nova Corona Borealis Star Explosion Dwarf Nasa
- Every 80 years, the skies grant us a rare gift: a stellar explosion called a nova that outshines all other cosmic wonders . This celestial fireworks show occurs when a white dwarf star erupts, increasing its brightness ten thousandfold. Even with the naked eye, we can revel in its glory from millions of miles away, and another show is about to start very soon. NASA scientists and astronomers are waiting patiently to see it, just like we've yearned to see solar eclipses and the Aurora Borealis ... [Read More]
