What telescope did HL Tauri use?
This is the sharpest image ever taken by ALMA — sharper than is routinely achieved in visible light with the NASA/ESA Hubble Space Telescope. It shows the protoplanetary disc surrounding the young star HL Tauri….About the Object.

What is the HL Tauri system?
The HL Tau system is located in the constellation Taurus, approximately 450 light-years away. It is less than 100,000 years old and about 17.9 billion km in radius. HL Tau’s protoplanetary disk is unusually massive and bright, which makes it an excellent place to search for signs of forming planets.
What is HL Tauri made of?
Young stars like HL Tauri are born in clouds of gas and fine dust, in regions which have collapsed under the effects of gravitation, forming dense hot cores that eventually ignite to become young stars.
Does HL Tauri have planets?
At apparent magnitude 15.1, it is too faint to be seen with the unaided eye. It is surrounded by a protoplanetary disk marked by dark bands visible in submillimeter radiation that may indicate a number of planets in the process of formation….HL Tauri.

What are Alma?
ALMA is a transformative radio telescope that can study cosmic light that straddles the boundary between radio and infrared. Most objects in the Universe emit this kind of energy, so the ability to detect it has been a driver for astronomers for decades.
How is HL Tauri similar to the solar system?
This image compares the size of the Solar System with HL Tauri and its surrounding protoplanetary disc. Although the star is much smaller than the Sun, the disc around HL Tauri stretches out to almost three times as far from the star as Neptune is from the Sun….About the Object.

How old is Tauri?
HL Tauri is a very young T Tauri star in the constellation Taurus, approximately 450 light-years from Earth in the Taurus Molecular Cloud. The luminosity and effective temperature of HL Tauri imply that its age is less than 100,000 years.
What kind of telescope is ALMA?
single telescope
ALMA is a single telescope of revolutionary design, composed initially of 66 high-precision antennas, and operating at wavelengths of 0.32 to 3.6 mm. Its main 12-metre array has fifty antennas, each measuring 12 metres in diameter, which together act as a single telescope — an interferometer.
What is ALMA telescope used for?
What is observed at HL Tau?
(i) The absence of spiral structure observed in HL Tau is due to the different response of the dust compared to the gas to embedded planets. Axisymmetric rings such as those observed are a natural product of embedded planets in the disc when observing the dust. Spiral structure may still be present in the gas.
What does the ALMA telescope look at?
ALMA is the most powerful telescope for observing the cool Universe — molecular gas and dust. ALMA studies the building blocks of stars, planetary systems, galaxies and life itself.
Who owns ALMA telescope?
The telescopes were provided by the European, North American and East Asian partners of ALMA. The American and European partners each provided twenty-five 12-meter diameter antennae, that compose the main array.
