New sunspot cycle could strongest record
2020/12/18
A team of scientists led by the National Center for Atmospheric Research is predicting that the sunspot cycle that started this fall could be one of the strongest since record-keeping began.In a new a...
A cosmic barbecue:Researchers spot 60 new ‘hot Jupiter’ candidates
A cosmic barbecue Researchers 60 new hot Jupiter candidates
2017/7/24
Yale researchers have identified 60 potential new “hot Jupiters” — highly irradiated worlds that glow like coals on a barbecue grill and are found orbiting only 1% of Sun-like stars.Hot Jupiters const...
Since the mid-1990s, when the first planet around another sun-like star was discovered, astronomers have been amassing what is now a large collection of exoplanets—nearly 3,500 have been confirmed so ...
Three decades ago, astronomers spotted one of the brightest exploding stars in more than 400 years. The titanic supernova, called Supernova 1987A (SN 1987A), blazed with the power of 100 million suns ...
New radio map of Jupiter reveals what’s beneath colorful clouds
New radio map Jupiter beneath colorful clouds
2016/6/12
tronomers using the upgraded Karl G. Jansky Very Large Array in New Mexico have produced the most detailed radio map yet of the atmosphere of Jupiter, revealing the massive movement of ammonia gas tha...
Astronomers have made a significant step toward confirming a proposed explanation for how solar flares accelerate charged particles to speeds nearly that of light. This important advance was made poss...
‘Upside-down planet’ reveals new method for studying binary star systems
Upside-down planet reveals new method studying binary star systems
2014/5/13
What looked at first like a sort of upside-down planet has instead revealed a new method for studying binary star systems, discovered by a University of Washington student astronomer.
The star system harboring the new planet contains only one star, as do the other three systems with extrasolar planets analyzed by Kane, an assistant professor of physics and astronomy, and his collea...
New eigen-mode of spin oscillations in the triplet superfluid condensate in neutron stars
Neutron star Superfl uidity Spin waves
2011/10/14
The eigen mode of spin oscillations with $\omega\simeq \sqrt{58/35}\Delta$ is predicted to exist besides already known spin waves with $\omega \simeq\Delta /\sqrt{5}$ in the triplet superfluid neutron...
The Solar Dynamics Observatory (SDO) was launched in February 2010 and is now providing an unprecedented view of the solar activity at high spatial resolution and high cadence covering a broad range o...
Quasi-Periodic Pulsations in Solar Flares: new clues from the Fermi Gamma-Ray Burst Monitor
Sun: fl ares Methods:data analysis Methods: statistical Methods:observational
2011/10/8
In the last four decades it has been observed that solar flares show quasi-periodic pulsations (QPPs) from the lowest, i.e. radio, to the highest, i.e. gamma-ray, part of the electromagnetic spectrum....
The formation of fullerenes: clues from new C60, C70, and (possible) planar C24 detections in Magellanic Cloud Planetary Nebulae
formation fullerenes:Magellanic Cloud Planetary Nebulae
2011/10/9
We present ten new Spitzer detections of fullerenes in Magellanic Cloud Planetary Nebulae, including the first extragalactic detections of the C70 molecule. These new fullerene detections together wit...

Techniques: radial velocities – Methods: data analysis – genetic algorithm Stars: individual:HD 104067 HD 125595 HIP 70849
2011/9/27
We report the detection of four new extrasolar planets in orbit around the moderately active stars HD 63765, HD 104067, HIP 70849, and HD 125595 with the HARPS Echelle spectrograph mounted on the ESO ...
A mission to study the Sun in greater detail than ever before has been launched today from Cape Canaveral, Florida. NASA's $850m Solar Dynamics Laboratory (SDO) will use a suite of extremely sensitive...
Using the European Southern Observatory´s Very Large Telescope (VLT), astronomers from the University of Sheffield have detected a stellar mass black hole much farther away than any other previo...
